You know, I don't care what anyone says and anyone angsty about this can go to Hell, but I think this keynote was pretty big for Nintendo.
First, they actually updated the Nintendo with demos and videos from the conference. Not only that, they offered an update during said conference.
I was underwhelmed by the lack of Wii announcements, but the updated SD supports, game announcements and new info on DSiWare make me excited.
