Well now that I've received the righteous speech - there's been no real answer.
Is there an extra something with the 64 that makes it better than the 32 other than space?
Or is it a case of 'we tested with the 64 because that was the only card available at the time' ?
Or no one has tested with the 32 yet? Any of those would be a real answer.

I just tested GH2-X 720p60 on a Sandisk 30MB/s 16GB class 10 card. I was able to get between 5 and 7 seconds on a take with legacy glass. Native m4/3 glass gave me about 2-3 seconds burst. With the 95MB/s 64GB card I get 10-14 seconds with legacy glass and 7-8 seconds with m4/3 glass.

If you don't need to span with 1080p24, I wouldn't worry about spending the extra coin on the 64GB card. I don't have one, but other's have tested the 32GB version and confirmed that it does not span 1080p24.

The 64GB card is the only one that can span 1080p24 with the highest bit-rate hacks. That's the only reason I got mine. I'm DP'ing a feature on a hacked GH2 in January, and I want to be able to reliably use the highest GOP-1 bit-rate hack that I can. Unless I can span, I'll be limited to a roughly 3 minute take at most. For most situations, that's totally acceptable, but during the feature shoot I'm bound to come across a scene where I need to roll for longer than that (this happened on two occasions during a short film shoot I did on a hacked GH2 back in September). I want to be able to roll for as longas needed and not have to explain to my director why we have to split the shot into two or more takes because of card limitations.

If spanning is weren't an issue for me, I'm having no problem recording SeaQuake on Sandisk 16GB Class 10 30MB/s cards, as well as older Sandisk 8GB Extreme III Class 6 cards.

It's also nice to get roughly an hour of footage on one card so I don't have to dump footage as often, but that's a tertiary benefit.

edit: Just noticed today that the price of the 64GB Sandisk 90MB/s cards have dropped to $189 on B&H. I should have waited a couple of weeks, would have saved 20 bucks!

@cowpunk52
Aside from Slo Mo, would there be any other reason to get a Sandisk 32GB Extreme Pro (95Mb/s) vs a standard Sandisk 32GB Extreme card (30Mb/s) for these high bit rate hacks then? Pointless to slap down the extra cash for the 32Gb 95Mb/s card for video?
 
I would say probably not. I can record SeaQuake 1080p24 just fine on this card:

I haven't tried the 32GB version, but I don't see any reason why it wouldn't work just as well. At this time, I would say that if you're not going to get the 64GB version of the 95MB/s card, then don't worry about the getting that class of card. The 30MB/s card works with all the hacks I've used just as well - you're giving up spanning and slow-motion burst performance, but that's about it.

The one variable that I haven't tested or accounted for is whether you're using legacy or m4/3 glass. I have noticed that the m4/3 glass chokes my slow motion burst much faster than legacy glass - and I attribute that to the in-camera correction processing that m4/3 cameras do with those lenses. But that's just a guess. I don't know what affect m4/3 glass with SeaQuake or Quantum 1080p24 may have on various SD cards.

As always, this is my experience and opinion. I have not done extensive real-world testing, just shooting around and getting a feel of what the cards are capable. You're mileage my vary. But at the prices that all these cards are offered for, you really can't go wrong with any of them (even the $190 64GB cards). They're an investment that will likely far outlast your camera and the price points are a song compared to proprietary recording media (*cough*cough* P2, RedMags, SxS *cough*cough*).

yup, Tyrell.
it's just my opinion, but best thing is posting a video once at the right place.. and be patient ;)
it will just make viewers disregard what you put your hard work on.
 
Thanks a million cowpunk52!
I am using a ton of legacy glass including leica M and iscorama's, but occasionally would like to pop a 4/3's lens on for the AF when using my steadicam pilot. I will probably pick up 1 card for that and a bunch of the lower spec ones for more normal usage.

Righteous speech? Wow.

I thought I was doing exactly what I said; offering a bit of perspective. I didn't think anyone would take it personally. You seem pretty stirred up about it. My apologies. But I am glad you got your real answer. And I hope you enjoy your gear.
