Wi isn't surprising. I didn't do a ton of shopping in stores for the holidays, but the few times I did go to some store, you could always see some grandparents lug around Wii boxes. I imagine there are a lot of disappointed grandkids out there. Found out during the family get together with the wife's family that just about all of them had gotten a Wii, and just about all the kids were disappointed that it wasn't a PS3 or 360. :'(
PS3 crushing the 360 is more surprising. I'm sure software sales do not show this in the slightest.
