I'm guessing they banned footage of the games they did because they're surprisingly unfinished (at least the builds at the show) given their launch dates and they don't want to tarnish the image of their big names. Though I never ran into any, I heard of SMG2 crashing, and the load times were pretty long. Also, all they had was a simple level select, similar to when they showed off the first SMG in Europe and also banned footage. I have to assume we'll get more Metroid footage at GDC, because it really doesn't make sense to not show this epic video in its full glory (it's kind of sad seeing it as a cell cam recording). At the event, not every attendee even got to see it. I was told that the level design wasn't quite finished, they had disabled all menus, and they said that the sound levels hadn't been normalized yet. I'm not sure if they're trying to build up more hype like this or what, but I think having everybody try to explain the experience with words only does the game a disservice. At least they aren't as bad as Square Enix. They were a lot more permissive about filming at this summit than in ones past. In previous years, we were limited to 5 minutes per game and had to include the controller in the shot. This year, we had no time limit, only had to have a bit of body in the shot (still silly IMO), and could do direct feed for willing third parties. And at least Metroid was hands-on. I wasn't even allowed to touch Prince of Persia, let alone film it.
