Nights 2 being a Wii exclusive made sense to me from the moment we saw the controller almost two years ago. Naka and other Sonic Team members always said that they'd never rule out a sequel, but that it would have to have a completely different way of playing in order to justify making it. Well, I reckon the Wiimote answers that call. There's a chance that the original game is made available on PSP and 360 as a Live Arcade download, but I can't see Nights 2 being on anything but Wii.
It's obviously real BTW...anyone with a decent pair of eyes can see that the Nights render on that cover is all new, with details not seen on the Saturn renders.
