Looks probable at this point, unless sales start to really drop of vs ongoing Halo 3 sales or a new CoD title calls a halt to its run.

Don't think it will as Halo3 sales still quite steady.
And the sales of MW2 will drop after holiday season is finished.

But Halo reach stands a chance I suppose.

Yes !

Halo Reach to Top 15 Milions xD

hopefully not...

Yes it will, sadly.

MW2 will destroy pass Halo3 sales

AND, more important

it will contribute to reduce the impact of the next Halo game that will look "too much Halo" compared to the piece of "realism" that is MW

In clear, time has passed since Halo was the master FPS franchise for the 360 and I m wondering at witch point CoD7 will steal some thunder from REACH

(dont worry, REACH will still be BIG)

It'll easily outsell Halo 3 although I don't want it to.

I don't think Halo 3 will sell past 12 million however MW2 passing 15 million is possible.

Pffft nsmbw>mw2 already

People underestimate Halo 3...

You know, the game sold over 1.7 million in 2009 alone? It'll manage another million in 2010, I can't see it topping off anywhere less than 13mil lifetime. Even Gears of War 1, a much smaller game, is still selling bits, making over 700k since Gears 2 came out.

For MW2 to pass Halo 3 before 2011, it'll need to sell 3mil next year. That's asking for MW1-type legs, which I don't see happening. If the game ever does pass Halo 3, it will not be any time soon (definitely not 2010). Honestly, I don't think it'll happen at all (due to the oversaturation of CoD titles), though it'll be close.

edit: Really just depends on MW2's legs, or how it holds up next week, or next month. If Modern Warfare 2 ends up like Gears 2 (recall Gears had legs like MW1), then its sales will plummet after the holidays, and struggle to find new buyers, because all the owners of the first game already bought the sequel. We'll have to wait and see.

lets just keep our fingers crossed :P
