Backwards compatibility. All three of the next-gen systems will be backwards compatible. However, the Revolution takes this a step further in that games dating back in the NES, Super NES, and N64 eras can be downloaded onto the system. Now THAT is cool.
I'm assuming that you'll need a special adapter? I wonder if there'll be an adapter for the Gameboy, Gameboy Color, GBA...
(hey, I wonder if I flipped my NES over, and cut some plastic... could I play the famicom cartridges?

Square-Enix. Final Fantasy is no longer exclusive to Sony this generation. The company announced support for the Xbox 360, and will bring that MMORPG Final Fantasy XI to the system. They will also heavily support the Revolution, as a Final Fantasy Crystal Chronicles is in the works. While neither of these games will be as good as Final Fantasy XII, it does mean that Final Fantasy XIII will not necessarily be on the PS3.
That's good to know. Square and Enix finally return to Nintendo. Bad side is, they've merged.

EDIT: Seems it was released last year. It probably won't be translated until this year..
