Well, the presentation's done and we're still kind of in the dark. Nintendo is following the drips-and-drabs approach again, with giving 'feel' presentations and then slowly giving out the information second.
What we can deduce:
Funky Controller? Check.
HD graphics? Check.
'Core Gamer' games? Check.
BluRay or DVD? Unlikely, but unknown.
Wii Compatible? Almost certainly.
Gamecube backwards compatible? Unknown, but highly likely.
Wii U / 3DS connectivity? Check.
I know we'd gotten snippets of this being the real deal earlier, but I'm still surprised at how different this approach potentially could be. With the advent of Move, though...we'll now see much strong support for motion controls in all games that's consistent.
