It's been announced that the next entry in the Scooby-Doo DTV (Direct-to-Video) franchise, #29, to be released on February 5 2019 is titled Scooby-Doo! and The Curse of the 13th Ghost. Why does this make me happy/excited? Because it will finally bring closure to the 1985 animated series The 13 Ghosts of Scooby-Doo which was cancelled before the final episode was produced/aired.
Yes, Maurice LeMarch will reprise his role as Vincent Van Ghoul after having voiced the character in his prior appearances in the series Scooby-Doo Mystery Incorporated where he was a local Crystal Cove celebrity/monster movie actor instead of the actual warlock that the character was originally created as when voiced by Vincent Price in The 13 Ghosts of Scooby-Doo.
No news yet on whether Scrappy-Doo and/or Flim-Flam will appear as well, though given the intense bordering on enmitous dislike of either or both characters from the SD community I'd doubt it.
