PS3 will do extremely well, but the fact remains that despite its lack of games, many people are willing to buy the Wii.
I think it'll be second in sales, and will pass the Xbox 360 in total sales at latest 1st January 2010.
In that poll we had a while back, I voted that PS3 would be at 20 mil by Jan 1st, with 360 at 23 mil. I'm beginning to think the 360 will be less- look what the 'price cut' managed to achieve
In a fair world, Wii would be far behind. But life isn't fair, so in holiday sales:
1) Wii
2) PS3
3) X360.
