If we see a trailer this year, i think it will be attached to assassins creed, so keep checking the bbfc/mpaa websites around that time, i'm thinking now we won't see one until early january next year. That news a few days back of reshoots, they're probably just standard pick ups considering they're being filmed in the u.k. but the last two years, it usually means the studio interfering over something they're unhappy with and thats what makes me think early next year for a trailer. Fox can't afford to screw this one up, so they won't release a trailer until they're 100% happy with what Scott and them have. They have to be very careful with this one every step of the way and not release a trailer with brilliant footage, which dosen't make it into the final cut.
