There is far too much interest in the film at this point (really, it must have at least four times, if not more, the amount of awareness as every movie it would've faced had it stayed there). Obviously releasing it on Christmas Day became too much of a risk, but I really doubt, after all this controversy and widespread outrage over it being pulled, that they would shelve the picture permanently. It's a tough situation (at least until the hackers are found), but I think there is little doubt this will eventually see the light of day (and if it does, and gets a wide release, it'll be huge now). It's going to be too hard to sweep a fairly big-budget movie that has caused this much commotion under a rug completely.
We'll see, I guess. It's all a big "if" at this point.
