Their definitely over due since the re-boot's were huge success's and now is the perfect time for them to green light a sequel to one or the other. With the Hellraiser remake and Child's Play remake still in limbo there isn't a reason why Warner Brothers shouldn't put the pressure to get these projects done. We fan's deserve better than this other drivel they keep tossing out way. They are supposed to be taking a less risk, higher rewards attitude which would make since with two hugely successful franchises. I mean has either ever lost money? And the cash flow they made off the remakes it's apparent to me and all the other horror fans out there that all logic is lost in their attitude.
The only people that seem to make any sense at all is Warner Brothers. It's still kind of early to tell for certain if Scream 4 will be a success, but even if the worse happens and it flops, it shouldn't effect there decision because as great and as legendary as the Scream franchise is, it's no comparison to the Friday the 13th and A Nightmare on Elm Street franchises.
Those two franchises are in a league of there own along with the John Carpenter's classic 1978 Halloween. There seems to be nothing happening on that franchise front any time soon either, but Halloween 3D would be another great choice if Warner brothers sleeps on their two main franchises. One company's loss is anothers gain.
If neither company get's the ball moving then I'm not expecting a very good year for 2012. Warner Brothers needs to revisit the Newline and Paramount's 1980's attitude. Back then they seemed to have a sequel of both every other year. Depending on these studios and their willingness to play ball will determine exactly how great we horror fans will have it, not only in 2012, but in the years to come.
