I have my doubts they will be on the Blu Ray, since they're about the original untouched films.
There may also be legal issues with MOSW, as William Conrad's original narration was replaced for the late 1990's VHS release. SPFX also had some movie clips cut out for home video. It also might be expensive to clear all the movie clips in Classic Creatures for a new release.
The original USA Laserdisc pressings are notorious rotters. Only the Japanese discs are watchable today. Classic Creatures and Making of a Saga were only ever released on LD in Japan.
There may be an announcement around here with regards to MOSW and SPFX sometime in the near future. Keep your eyes open. ;)
