I can't wait till the 19th. It might be quite possible that Nintendo didn't divulge everything at their Japan 3DS conference because they wanted to save some tidbits for the Western conference.
I personally think Nintendo did incorporate a universal friend code, if not a username. Nintendo has put in a huge amount of effort to woo 3rd party developers. I'm sure they had extensive dialogue about the importance of a universal sign-in for better online play and for DLC.
I personally don't care about achievements, but maybe Nintendo does have their own version of achievements in store for us.
Most anticipated games of 2011:
Uncharted 3,Legend of Zelda: Skyward Sword, Rocksmith
Modern Warfare 3, Super Mario 3D
