I'll go ahead and start eating crow:
At least for now and in NA, it'll beat Zelda. I don't think Nintendo can push 1 million units, even before the end of 2006. Of course, I'll still bet on Zelda for the longterm and worldwide. But if that initial sell thru is anything, GOW will keep trucking. Everybody is talking about it. Hell, I want to play it. MS, drop the price, you douches.
