Hmm... maybe I should go then, I've been debating it - would love to be there for some sweet nintendo announcements. I have a feeling they will try to shift the focus away from DSi/Downloadables to the Wii from GDC to E3 but its just a guess.
Currently dreaming of: DKC4 or Sonic the Hedgehog 4 (classic 2D platformers) for WiiWare, Smash Bros. for DSi, New Super Mario World for DSi, a Wii remake or true sequel of Final Fantasy Tactics.
One down, hopefully more awesomeness to come.
