Kirby Wii - preview

From Joystiq's article based on their E3 experience:

As with Epic Yarn and other recent Kirby series entries, Kirby Wii's platforming and creature battles are light affairs, demanding little more than a bit of very basic puzzle solving or well-timed actions in the few levels I played.

You can suck enemies in and shoot them out, you can destroy them with one of Kirby's many hat abilities (such as a giant sword), or you can shoot them at each other. There are also blocks, which you can totally suck up and ... you get the idea. It's very unlikely you'll meet your demise.
