Maighstir: 4K-screen, everyone can play in full HD :-P
Actually, that would be nice, I should get a 4K projector to replace my current 720p one.
tinyE: A tad OT, and assuming you know what a Jumbo Tron is (I know Europe has them but they might have a different name), a few weeks ago I saw a Make-A-Wish story about a kid who got to meet his favorite player and they went out onto the field with two chairs and actually played Madden on the Jumbo Tron. XD Way Cool.
It's not like large displays are required for split-screen though. Many who played
back when the Nintendo 64 was new and hot had TV's with screen sizes that would be almost unthinkable today.
