The reason why Gears 1 sold so well was because it was closer to launch of the 360 and had great legs due to MUCH less competition. I remember when Gears 1 first released it was all everyone was talking about. Now you've got those same people who are going to be busy with MW3 and BF3; MW3 having a massive amount more appeal than Gears and BF3 having much better quality. With these two games on the market it's going to be harder for Gears 3 to maintain great legs. Not saying the sales overall are going to be bad (look at the pre-orders) it's just not going to hit ten million, IMO.
