OK. This is for all of you who are worried about reviews, marketing, and so on. I'm calling it now. $675M (US) and $1.2B (OS) for a total of $1.875B. Passes Titanic in both categories (initial release) and puts Avengers at # 2 and 3 all-time in US (not counting re-releases). I think it's going to be HUGE in southeast Asia.

That's all but certain at this point. You should see the displays and the advertisement crusade in Hong Kong; it's nothing short of ridiculous (in a good way).
