the point in this because, for gaming in say MW2 or CS:S, you arn't interested in anything further out than a single monitor provides. The good players don't look around, they look blankly at the screen until they see something move and then twitch to it. Given that screen space of this vastness is going to put more of the game to your peripheral vision, i can't see the advantage. I'd be very surprised if you went to LAN parties and the 'elite' players used a setup like this.
It does have its advantages for strategy games however where more screen real-estate is valuable and for movies, but for that to be any fun to use manufacturers will have to make specialist monitors with no screen frames.
