Unless were overtracking 3 and Reach, of course.

Show me a single piece of news from Microsoft which say reach or halo 3 or halo 2 or halo 1 has sold 10 million.

Surely they would publicise that milestone

The latest published milestone for Halo 3 was 8.1 million in early 2008.

I'm sure it sold more than 10 million to date.
