well, I know I'm not representative of hte general population. but I've had a Wii since August '07 and have yet to buy a game for it. It almost never gets used at all except my dad bowling a few games about 3 times a month or less. I WAS interested in MK because I loved it on the N64 and the Cube, but then Nintendo had to make it so you can't so a free-for-all (the reason I loved the other games) and I didn't get it. (Wipeout HD and Burnout Revenge are more than enough to satisfy my desire for more traditional racing games)
Also, with the tremendous amount of games coming out for the PS3 in the coming months, I don't see this changing anytime soon. However, I am keeping the Wii in case the day ever does come that a game will come out for it that interests me, but at this point, there are none forthcoming that interest me in the slightest. Based on that (and I realize it is just my opinion), I'm going to say it is becoming increasingly unlikely that PS360 owners will buy a Wii.
Not trying to be a fanboy. Of course, it's hard when you own the best console eve... dang it
