I am going for the MW console, however the gears console is basically the same thing, depends on which game you like more or which design you like more. The bundles are a good value, especially if you can sell 1-2 things out of the bundle in order to get some of your money back. Even if you don't, it still costs more to buy everything that is in the bundle at retail. The extra space on the hard drive is going to be an invaluable asset for me at least.
The gears console seems to be sold out everywhere around here at least, so I am definitely preordering the MW console from either amazon or gamestop, most likely amazon. I assume its going to be impossible to find the MW console here as its easily more popular than Gears.
The star wars bundle releases later on, and comes with kinect and a star wars kinect game, however the price tag on this bundle is higher and you only get one controller, its not a good value for someone who doesn't care about kinect or who doesn't have enough space to use kinect. If I wanted kinect I would just get the regular $250 GB bundle that is supposed to drop in price to $350.
