Is Gears of War 2 going to be bigger than Halo 2.?

[Dallinor]

I think advertising will play a key role. Will microsoft spend another 10-20 million on advertising for the title?

I expect at least 70% of the install base of the original will re-buy if the game gets good reviews.

So it could end up with LT sales anywhere between 5-7 million.
