MW2 is meant to be in september some time, L4D2 will probably be around christmas though im not sure on that.
EDIT: Just checked Wiki, MW2 is 10th Nov and L4D2 is 17th Nov. That's if they stick to the deadline. TBH, if we get a CSS and TF2 server now, there's no point getting some other servers just to have to switch them in a few months. I don't mind waiting.
