Thinking about it, new HW doesn't rule out anything that's not a console, so I think they might want to focus on the Wii Vitality Sensor at GDC if they plan on releasing a Wii Vitality game right after E3, hype needs to build up.
Of course, last year they didn't even show WM+ at all, so this will be a wait and see scenario.
But I still believe DS2 will be announced this year.
