I'll go you one better and tell you what I did actually pick up today:
Dark Sector
Blue Dragon
Kane & Lynch
I've been playing Dark Sector since I got back from the store around midday... It's been a real surprise, this game is fun as hell! If you liked Gears, the controls will immediately click...
An extra $100 extra nets you an extra wireless controller, Gears of War, and Madden '07. If you're the sort that can live with last year's version of a sports title, pretty nice deal, 'bout a $40 savings.
You can also get PGR3 for $5.99 with the purchase of any 360 product priced $25 or more...
