I don't believe those are official screens of what the controller will actually be used for.
I know for FPS' you'll probably just use the remote to look around.
But why would you twirl it for an attack in Smash Bros? That's just downright stupid and unlogical.
Also, look at the actual file name for those first few pics "Revolution-Controller-The-Possibilities" All IGN did was photoshop on the hand holding the controller over games already made/game screens that have been previewed and it's what they imagine you'd be able to do with it.
Waving your arm around for an entire hour would just be tired, we all know it, Nintendo knows it, so I'm sure they won't make it like IGN said would be "Possible". They're Nintendo, they care about their customers, they wouldn't want us to just play for an hour and stop because we can't go doing a spinslash with link in Smash Bros anymore
This controller is one of the most innovative things I've ever seen, Sony and Microsoft are playing it safe by sticking with standard controllers, but Nintendo has some guts for making that.
Also, don't forget this IS still just the prototype, things could change.
Either way though, Revolution now has my full support, right on to Nintendo.
Now if only they would release some screenies for some Revo games!
