Not to mention you also need a second TV, and if your not doing LAN, a second LIVE account. If you were to set up a LAN for playing games over the two systems, would you have both TVs in the same room, or would you keep them in the rooms they're in and play in two separate rooms?

I spent a lot of quality time playing NES with my dad when I was a kid, Pac-Man was our favorite multiplayer game. But I don't think it would have been quality time if he and I had been playing from separate rooms. I'd rather loose screen space with split screen and keep the enjoyment of having the people I am playing with at my side.

Of course, a setup with two TVs back to back in the same room would be pretty sweet.
