If Nintendo was serious about talking up their new console/platform at GDC - which is early March - they will almost certainly announce it before hand.
Any new platform announcement will probably come with games... how about a new Pokemon title to kick it off in style?

Timing doesn't make any sense for Zelda IMO - its going to be a Xmas title... they will wait till E3, and then really ramp it up 2-3 months before release.
