Delurking for the first time in ages, I'd like to chime in here with a note to Paramount,
If they aren't uncut, I'm not buying

no matter how much extra material they include.
As Will K already mentioned, It's doubtful any jaw dropping information will be spilled on September 19th, but I'll be online just in case!
Sadly I don't hold out much hope, we all know what happend to "My Bloody Valentine" & the requested uncut release by MBV's producer John Denning (Who interestingly, found ALL the gore trims & scene extentions totalling 8-9mins!)
It's a crying shame they won't sub-license these American mainstream horror classics in full bloodied versions & quite frankly it's a slap in the face for Friday fans who have made them an unholy cash cow for Paramount.
This all takes me back to when Part 6 ("A lad Insane" IIRC?)was being filmed, a film journalist friend was on set & while most on the production gave the impression they were proud to work on it, several suits from Paramount came to set putting people down & ripping the F13th series to bits, very sad.
Anyhow, worst case scenario, they'll include rough quality work print versions or worse still the MPAA cut footage, which would amount to what, mere seconds, lumped together in a supplement at the end of each film

You'd think the box office takings for "Freddy Vs Jason" & the forthcoming uncut F13th SE on R2 UK dvd would make Paramount dig deep into the vaults for the definative versions....
