So I got DeBlob. If you own a Wii, you should at least look into it. It takes the freeware tech demo and makes it way more awesome. It's not a system mover, but it's really cool. I dig it.

Also, I kinda want Disaster, only because it's going to be sooooooo cheesy. I know it'll just be waggle shit, but I've always wanted a game based on natural disasters and shit.
