You know, I'm quite excited for the Wii HD. My reasoning being is that I want the Nintendo exclusives playable on my HD monitor. Sure, I could hook up a PS3 or XBox 360 to my office monitor, but a lot of the games available for those consoles can be played on a PC.
So, yeah, Nintendo Wii HD is what I'm excited for!
Cooler N3DS games to make me consider buying it
Uh... Thats about it I guess. The Wii and the DS are the only game consoles I really follow. (Unless comps count now)
