It'd be sweet if the panels move to flatten the screen for showing the large trailers / gameplay, then separate again for the montages/background stuff.
You know that modern projectors work in a way where they can make that an unflat surface appears like i a big flat screen no?
Nintendo last year used that technology for the conference, when they showed the 3DS reel games and appeared like if it was some kind of 3D prejection.
Disney uses it alot in their theme parks.
