Alright so you can play 4 player splitscreen on Halo 3 and that's cool. We know that the box can handle 4 players playing with it's multicore CPU and GPU. What if there was a peripheral that allowed you to connect multiple screens to one console? I would love this. Yes MS won't do it because it would theoretically discourage console sales. But would it really?? I mean I want to just play some Halo 3, or COD 4 with friends and not be looking at Gameboy size screen. That doesn't mean my friends won't get a console to play at their discretion in their own home. It only means we don't have to haul our boxes around all the time to game together. I would pay about $100 for this multiscreen peripheral. What do you guys think? I think it's totally possible, even if you would have to upscale portions of the screen to fit into a fullscreen/widescreen.
