I think that Gears 3 will have the highest opening week sales of the three and Syward Sword will have the strongest legs and will have the highest lifetime sales.

I just want more info on all of them before I can say for definite, when is the release date, and WHERE ARE THE SCREENS FOR SS!!!??!!

You know...you have a great point :).
