It started far better than Fable 1, about 3x the sales, so i bet will surpass 3 million worldwide 

What do you think ?

certainly...

Most likely, I see no reason for it not to.

Well, it has succeeded in selling approximately 1.6 million copies in three weeks and five days - that's good and I would not be astonished if it did sell more than three million copies.

It should be able to.

Considering the worst-selling X360 game to debut anywhere near a million sold 4,000,000 games an counting...The answer is yes.

Easily, it has a very good chance at 4 million+.

well less than a month out and its already half way, should pass 3 million in a few months...

It is possbible indeed, given it has sold 3x more than Fable 1 did in the same time frame

Also is not released in Japan yet, and the new DL content will definatly increase sales even more, especially since those that pirated the game will now have to buy it to have the full package

Definitely.

I don't think it can cross 4 million though.
