I would love to witness some RTS titles with that many screens. Something like Supreme Commander with tonnes of units would look incredible. If I were a game dev, (and christ knows how much I wish I was.) I would be looking to create an RTS title that took advantage of that many screens.

Being able to dedicate certain screens to a first person view of the battlefield, whilst others displayed statistics and a general overview would be awesome. How cool would it be to have a screen with just icons of fighter jets that disappeared when the corresponding unit had been destroyed.
