Er...why should it. They've got a humungous amount of computing power to scale the image. And a much faster readout of the sensor. They may even avoid pixel binning by de-mosaicing then down sampling.

We'll have to wait for test footage to find out, but the dual Digic 5 processors should allow it to handle much more of the data from the sensor than its predecessors and reduce the amount of hackery needed to get a 1080p feed from an 18MP chip.

The highest resolution this camera produces is still only 720p.

True, but if the full sensor could read/reset at 30 fps, and also downsample to HD at the same time, then they would have a higher continuous shooting rate than 14 fps for stills with the mirror locked.
Otherwise, it's line skipping... maybe they're skipping fewer lines, like sampling every other line and then downsampling from there. They claim to have "reduced" the moiré problem.

they said this about the sensor (from canonrumors forum):
DUAL LINE READOUT:
"The new sensor has 16-channel, dual line readout, compared to 8-channel, single line designs in the previous generation of chips."
I have no idea what all that means, but it sounds as if it is doing "2x2 to 1" or "2x1 to 1" binning in sensor, then demosaic in digic5

I guess you could call it a 2160p camera if you are satisfied with 12 frames per second.

Is there someone we can ask for info about the bitrate and color space? It seems like they would be willing to give out this information if they have already given out so much about the inter/intra frame options. Sounds like it's just a matter of asking someone at Canon for better clarification. Anyone know anyone there?

My guess is since the camera won't be released until March of next year they are leaving their options open regarding the video bitrate.
Kudos to Canon listening to their pro users. Its takes some guts to Lower megapixels in the marketplace.

I totally agree. I LOVE that they are doing a LEGIT pursuit to address the TRUE NEED: Sometimes I need EVERYTHING that the sensor can give me, no matter how HUGE the file is....and other times, I need a solid codec/bitrate that is space conscious.
FREAKING AWESOME! I understand that the implementation may or may not be the greatest (we'll find out soon enough), but I MUST tip my hat to Canon for taking the right approach.
I also think that some peeps around here may have to "chill out" a little bit when it comes to Canon. I sincerely LOVE me some Panasonic, but Canon is the one innovating when it comes to video on DSLRs. I'm NOT flaming Panasonic here (I own a GH13 and love it). I love me some Sony too....but they were so late to the game. (I own 3 Sony's, so no flaming there either). Nikon (which I also have owned) is not really in the game yet, and I'm not sure they have enough video know-how to ever be in the game.
Canon is the DSLR front-runner....like it or not. Panasonic, Sony, and Nikon have all had their chance to RESOLVE the video codec issue.....all Sony had to do was NOT cripple the Nex5N by making HDMI capture feasible (the same as the HX9)....but they did it anyway. Too bad that they left the door WIDE OPEN for Canon. If this codec is HALF what its numbers say, and if the moire and aliasing is under control, the others will either "join the club" next product iteration, or I won't be buying the GH3, period. It will be the Canon 8d, T4i, or 5dMIII.
Before anyone freaks out....I know that there is are plenty of "ifs" in my statements.....but my point is: Canon is taking the right approach (that no one else is) by having a two-tier codec/quality paradigm that includes POTENTIAL cinema quality footy....(even if it's freaking huge files). Kudos to Canon!
True. I am assuming that they will continue to do what they did with the 5dM2, 7d, T2i....which is that the video is NOT different as per implementation (IE: not crippled) There are differences, but they are hardware related. You are right. That is an assumption.
I will say for me (personally) though....I just may buy the 7K version anyway. I am a photographer and I make more $$$ from that than I do from video, so to have the best (one of the best) photo cams in the world AND a solid cine cam....geez, 7K sounds pretty good to me. Cheers and good point.

Lower megapixels but larger photosites. Guys, bigger isn't always better. I personally don't want a 32megapixel canon sensor. Lenses have a hard enough time resolving to the 5d's 21megs. I'm more interested in larger photosites with higher bit depth for still photos. I've had 10 megapixel cameras smoke 18 megapixels in image clarity. Same for video, I'd rather have a 50Mbit 422 over a 160mbit 420. But I'll settle with a 100mbit 422. I'm hoping that Canon has figured out how to pack a CR2 raw into a video camera. The 1Dx has all that processing power in it. Imagine a larger body video cam with 2 or 4 quad digic5's in there taking raw images at 1080p up to 120 frames/sec or up to 4k up to 30fps? The 1dx can handle 12 18MEGABYTEs per second RAW with a mirror in it. Thats crazy processing! Let's see Nov. 3rd. Speculation is easy.
I'd need to sell off some other equipment to really justify the investment, but, I can sincerely say that it is a more sound investment for me than an FS100. I'm not saying that the FS100 isn't BETTER (obviously we'll see, but I would not expect that), I am saying that having a "hybrid" cam that is slanted towards photo and capable as cine is looking like a solid move for many of us. I'm also certain that it doesn't make sense for others. I'll also say that the 5dMII has retained its value like a freaking BEAST. I can't believe what a used 5dMII is selling for today. I suspect that this cam will hold its value EXTREMELY WELL also. Anywho....we'll all get to see what Canon brings to the table in March.
The burst mode would run for less than 5-7 seconds since it will fill up the buffering very quickly.

I agree. This sounds like the camera that might give people a lot of what they want - full-frame, low-light, low or high compression. And, as you've said, hopefully they've nailed down the issues regarding aliasing.
And we can only hope that future iterations of their S35 cameras will include many of the same features.
And I suppose this does prop up whatever is coming on Nov. 3 as something to really look out for. It'll be very interesting to see if canon goes from 1/3" HD cameras to something...well, a lot more future focused.

My T2i sure hasn't. I bought the body-only new for what? Something like $850 when they first came out? They go for $450 used all the time now. Factoring in the difference in eventual resale value between the T2i and the 7D, it probably would have made sense just to buy the 7D to begin with.
I think I lost $350 or so when I sold my 5DM2 (last year).
