Gears of War Review

So now that a few in (and out) of the office have the Xbox360 up and running, the talk of games has increased 10 fold (as has my purchase of games). Next big release appears to be Gears of War, and I was subjected to a quick video of the gameplay last night by XTonks360 before I was allowed to leave the office. It looks pretty impressive, and a lot of fun - the release date is rapidly approaching, and someone has a hands on review of playing the first 3 levels. He doesn't seem like he's 100% convinced, but I'm sure there'll be more info and reviews in the coming weeks.

Now can someone tell me if it's worth buying Call of Duty 2 for 40 bucks, or wait until Call of Duty 3 comes out in a couple of weeks for 60 bucks?
