Who will surmise? Halo is coming out November 6 and Black Ops November 13. They have different fan bases...but one could tug a lot from the other. Do you think they'll bear any effect on sales and multiplayer activity?
I play and enjoy both. Sooo, oh well. I really like CoD's multiplayer, and most of them have had great stories, but Halo has had the best story so far in my opinion, and the multiplayer is pretty good. They are even in my eyes.
