Anticipation builds for Iwata's keynote address

Frequent tipster, Andrew, recently highlighted several of the rumors that are circulating Internet forums concerning Satoru Iwata's upcoming keynote at GDC.  While there is no way of knowing what the Big N's fearless leader will really reveal (or not reveal), several hot topics include:

1. DS online capabilities

2. The next (Gamecube) Zelda game

Can we expect more details on some (online?) DS games that will rival the PSP's stateside launch?  Metroid Prime Hunters?  Mario Kart?  How about a new Zelda trailer?  We will know soon enough...

[Thanks, Andrew]
