Know what you want in Modern Warfare 2? Tell Infinity Ward
Infinity Ward's set up a Twitter feed for suggestions about what to include in Modern Warfare 2, due for release at the end of this year.
All you need to do is add #mw2 to the beginning of your message and get involved. There's a constant flow of posts on that page, and it's quite fun to watch if you've been up half the night feeding babies and you're a bit boss-eyed.
Take a look.
