XBox 360 is heading into its 8th year. I give the XBox 360  a 50-50 chance of selling 10 million in 2012. Probably 9 to 10 million sales for XBox 360 in 2012.

PS3 will be heading into its 7th year but is on track to sell over 10 million sales in 2012. PS3 sales between 11 to 12 million in 2012.

I thinks they almost certainly will. Wii U should have an affect on sales but how much depends on the price they launch at. If they launch at around the same price as 360 and PS3 then it will take a few sales away but even then I think both consoles will reach 10M

Both will. Easily.

They'll do more than 5m in the last quarter alone.

Pretty sure they'll both easily do it. PS3 did 14 million last year and X360 did 13.8, they are selling less but I highly doubt they would both be 4 million less.

PS3's coming out with slimmer cheaper PS3 this year though, gonna be just as huge as the last slim was.

Shipments easily
Sales both should easy unless unforeseen circumstances.

Yes easily as most have stated, Don't count out a 360 price cut this year though.
