I sold my PS3 to get a Wii (if I ever see one in a store again). A couple of weeks ago they had three at my local Wal~Mart, but the last time I was there last week it was down to one, and I would say it is probably gone now, and there's usually about a gap of 9-12 months before I see Wii's back in the stores around here.
And I think I'm going to pick up an original DS off of ebay. Then, when enough DS Ware or DS vc games are out to justify its purchase, I'll get a DSi.
Heavens to Murgatoids.
