Looks like its pretty much a go after all these years. 8 now to be exact but no Neve this time around and its looking like a reboot.
The Weinsteins are quoted in there and since they were the brains behind the franchise besides Craven and Williamson. I'll pretty much take their word for it.
Not what I had in mind and being one of the few 'Scream' fans on the board. I can say I always wanted it to remain a trilogy, especially with 3 being as wishy washy as it was outside of the opening sequence.
