A reason to be jealous of the PS3 and Xbox360 guys:
Alas, no Wii version. I know it has souped up graphics and all, but it can't be SO taxing that it wouldn't run on Nintendo's console. It's almost a bit of a slap in the face that it isn't on the Wii... almost like what was going on with the whole GoldenEye on Xbox business.
As for the trailer itself... all I can say is "Woo!". The new graphics and abilities look sweet, and the enhanced gameplay mechanics add an entire new dimension to the game. I'm dying to play it... damned nostalgia tugging bastards. And even better... you can unlock the RAD character for the full blown sequel coming out (which addresses my one main gripe about the next gen version of the game).
At any rate, maybe it's time to consider a second console... ;)
