I call a Zelda announcement.
His last two GDC appearances had Zelda trailers, with 06 having the revelation of Phantom Hourglass.
I expect the speech to be in a similar vein to 06-people not expecting the success of Wii Sports/Fit, potential of WiiWare, improving online, possibilities of new control schemes.
Overall I'd like Iwata to follow a theme of "Nintendo will lead, third parties can follow us" in relation to a wider range of Wii titles, especially core titles.
Should be an interesting and insightful look into the mind of the man who's changed the industry dramatically over the last few years. Looking forward to it.
EDIT: also, be interesting to see what he says about Wii Fit/Mario Kart Wii sales in relation to GTAIV.
