Well, it's been awhile since COD4 and Halo 3 did the flip-flop on Major Nelson's ranking of top games on Xbox Live, but it's happened again: Halo 3 is number one, and COD4 is number two. Again.

How long that lasts is anybody's guess; perhaps the two games will get back on the seesaw. Until something else comes along to unseat them again (however temporarily-- the only game on the horizon I see that can do this is Gears of War 2) the determining factor on a week to week basis might become DLC.
