The only unfortunate thing about this is that we all know the games won't look nearly that good. Tech demos can be spiffy, but it's rare that subsequently released games look as good. You don't have to worry about things like size limits of the media when you've making something that's 30 seconds long, or having too many sprites on screen when everything that happens is up to people who have their eyes on what the hardware is doing.

I have to say though, the chance to see Heidegger in all his splendor at that level of detail...

Okay, suddenly I'm for a remake of FFVII.
