Halo 3 may be overtracked btw...

Microsoft have been very low key in Halo 3 sales, it was like 8.1 million January 08, that was nearly 2 years ago

I would think they would have announced it if they had shipped 10M. Its too big to not announce... Thats my reasoning anyway.

True but Halo 3 was still selling well early 08, that with Christimas 08, surely its sold more than 1.9 million in the last 19 months?
