M and S will sell at least 6 million copies. It will sell over the Olympics, and next holidays. 6 is a low ball number too. Could easily see it selling 8. DS version could sell 4...
10-12 million combined... also there are other benefits for sega because of the bigs sales. Namely Sonic is becoming a household name again. This will be HUGE when Sonic Unleashed is released.
psn- tokila
add me, the more the merrier.
