Received my quarterly (I think it's quarterly) booklet from GameStation and for the first time realised the both Gears of War 2 and Call of Duty 5 come out on the same day.

Which may leave some debating which to get.
I'll definitely be getting CoD5 on launch day, possible Gears, but I don't know when I'd find time to play it with CoD5, that's going to take a lot of my time up . I might get it in case I want to play it though .

Which one will everyone else be getting?
