Is 3 Call of Duty games in less than 2 years overkill? If not, it’s awfully close.

Simply amazing. Just totally, out-of-this-world amazing. Activision is said to be working on no less than three new Call of Duty games, to be released before 2012. That's three games in less than two years. You'd think that Activision learned its lesson with Guitar Hero. Remember when Guitar Hero was white-hot in 2007? The game was everywhere! Now? Is there anybody left on the planet who has any interest in the game, or the genre as a whole?
