360 > Wii > PS3

Wii>PS3>360

360>wii>ps3

Wii>>>>PS3>/=360

PS3 > Wii > 360 (I will laugh if I get all three in reverse), I know I am most likely going to be so wrong, but hey....that is my prediction.

Wow, this is actually very divisive.

Operating on the assumption of a PS3 price cut (which is almost inevitable):

PS3 > Wii > 360

Three of those four are multiplatform

Its so hard to predict this early, but my guess would be the one that has a price drop closest to holiday shopping. I think PS3 and Xbox might both have a drop right before shopping begins.

PS3, Wii and then 360. Wii will decline further, PS3 will do wonders with atleast a 50 euro pricecut. 360 won't do bad either but the Kinect rage is over.

Wii, mainly because the holiday is Wii's territory and because neither of the HD consoles' official price cuts will matter due to retailer cuts. When Wii touches under $99 with deals, it should sell quite a bit more than HD consoles at 100 bucks or higher.
In fact, if Just Dance 3 explodes in the same way as its predecessors and becomes Wii's CoD for this year, I'd be willing to bet that it'll top last holiday this time. Of course, that's what I thought last time.

With America's influence on the holidays, though, I can see 360 in a comfortable second place like last year.
