Same here. I'm holding out right now because I still don't have the final Sims 2 expansion, but I uninstalled the Sims 2 a month ago due to space issues, that and I had to bulldoze my favorite house due to a glitchy robot (no offense intended) that left undeletable/uncleanable dirty plates everywhere. The Sims 3 doesn't really look that impressing, but I'll end up getting in within a month.
The Wii version is supposed to be cartoony and more "game" like I suppose, not the real-looking thing.
