More than a milion the first week.
4 milions in his lifetime.

Either you are feeling extremely generous, playing Devil's Advocate, or both... o.O

I really have my doubts after the negetive wave of reviews.

I would have said more than a million first week EZ 2 Weeks ago...

My how time changes things...

I will say 800k max release week.

3.5 millions over 5millions is very unlikely.
And i don't think the games sales will be hurted by review

5 million, don't forget it will keep selling digitally. Escpecially if it discounted during (holiday) sales.

1.5m-2m

I think it will ultimately settle around that: despite the negative US press, it seems fairly well-received in the EU and is also being bundled over there.

Anything within 2 million is fine by me.

You're probably right but if we consider that the preorders should be 500/700 k, i Think we're very near to a milion.

2.5 million! A higher number than that is not impossible, but a bit unlikely!
