Nintendo can't say anything during GDC now. :(

Kwaad said: It's all about hype. Microsoft and sony are getting hype from this. Will Nintendo be able to do anything at E3? Holy crap, lucky for nintendo the E3 delay!!! If nintendo cant do E3... I will seriously die laughing. Because that would be so horrible... I wouldnt even wish it on them.

Any thing Sony and Microsoft announce at GDC will be only covered by the gaming press and a handful of main news outlets (as always) ... If you want your announcement to hit the general public it must be made at E3 (for western consumers) or TGS (for Japaneese gamers) ... I think you overestimate the importance of GDC as a way to build hype
