I follow boxoffice as a bit of a hobby and I believe STID would've done better had it not been so long between ST09 and STID.
ST09 seemed to have good word of mouth and audience enthusiasm, and then we heard nothing for several years and I think the franchise's rediscovered "hotness" kinda cooled.
So I think ST3 will do well, but it depends on the advertising campaign, and more importantly: word of mouth.
Poor reviews will sink the movie because Star Trek has been regaining some momentum but it's still a fragile franchise IMO struggling to get over the franchise fatigue of the Berman era, not to mention it's "uncool" reputation during the 1990s.
