Question about Panasonic's pizel shifting

[DBP]

I know that 1080p on this camera isn't true 1080p, more like 1440x810 worth of detail.

Now I read that there's three 960x540 chips that are creating this image....so my question is, in 720p mode, is it a proper 1280x720? Or is there some sort of up-res going on similr to the 1080p mode?

This may still be the case:

FYI, we don't know the sensor resolution, as Panasonic hasn't published that. Any claims that each individual chip still 960x540 are speculation. I happen to think it's probably accurate speculation, but I'm just pointing out that as far as I know there's been no confirmation about that from the factory.
