Finally getting a "new generation" console

Can you guess what it is? Well, it's black, and has a 250GB hard drive. Yup, a 360! On the night of July 16th - when then 360 250GB releases in the UK - I'm going to pick it up, along with a copy of XBOX live gold membership and Call of Duty: Modern Warfare 2 (because my friends all play it and I want to join in the fun!)

So, if you have any recommendations of games, last resorts to get me to switch to PS3 (which is unlikely) or random congratulations, feel free to leave a comment.
