@Pezus: yes!
- It's a FPS (and we know how FPS are loved this gen ...)
- It's the most beautifull console game ever
- It's a console exclusive
- It will be well advertized (2 million pounds for the UK alone).
So yeah, sales are way too underestimated.
And BTW, the game will be a hit too in japan (for a fps!). See preorders^^
