I want a 360 only for arcade. If I ebay a ps3, then I'll buy a 360 with my wii. Pretty awesome how that works out.
Pretty much Dead Rising and Geometry Wars (and I had access to the money) got me to buy my 360, so I'm kinda right there with you.
I have to say that I'm really all about the "Wii60," so you'd be wise beyond your years to go with it.
Now we're friends.
