Two sequels to popular horror franchises are coming in the 3D format, but one is coming much sooner than the other. Box Office Mojo recently listed release date shifts and it seems that Friday the 13th Part II 3D has been put on hold, with a TBD release. The site also announced, though, that Saw VII 3D has been locked in for an October 22, 2010 release.
Friday the 13th Part II 3D was originally set for an August 13, 2010 release, but it seems they felt they couldn't hit that date. The film will be written by Friday the 13th remake writers Damian Shannon and Mark Swift.
