It's being released in between Ass Creed 3, RE6, CoD: Blops 2 and Halo 4. I'm afraid it's being sent out to die.
No, it's not being released "in between" any of those games.
Dishonored is being released on October 9, a full 3 weeks before the release of AC3 which is the earliest release date of any of those games that you listed.
