Oh yeah Halo Reach will beat MW2 sales in both debut and lifetime on 360. I expect Reach to do 7-10 million day one. Lifetime = 16-18 million.

LOL...that might be a bit of a stretch for Day 1 sales...maybe Week One at 6-7 million, imho.  I'm not sure how people are coming to the conclusion that MW is now bigger than Halo...can somebody explain it to me...and saying "Look at these week one sales..."  is a riddiculous statement...I'll point out hte attach rate of Halo 3 vs. MW 2 isn't in the favor of MW.   

Attach rate at launch or LTD?

Because if you just mean generally LTD, then that's also a ridiculous statement as MW2 has been out for approaching 2 weeks now whilst Halo 3 has been out for over 2 years now...
