In regards to this, something occurred (sp?) to me earlier today.
Hasbro reclaiming the rights to the Sunbow catalog based on their properties can be either a good thing, or a bad thing. Despite having an entertainment division, Hasbro is a toy company first. For this reason, they actually have better things to do...like selling toys.
That being said, since they have the distribution rights, this means that they have the final say on who can release a DVD of "their" shows, as well as how, and when. The way I see it, this has the potential to be another "Get-Along Gang" case wherein somebody wants to release a certain show on DVD, but Hasbro won't have it, and that would be the end of it. Also, even if there was to be any DVD release at all, now that Hasbro owns the shows based on their properties, this puts them in the position of ordering that a show be released a certain way. You heard about that special edition Optimus Prime toy coming with a DVD of the first TV episodes, right? Hasbro could limit such releases to that for all we know, or for the ones that have been inactive for some time (such as Jem), they may decide not to allow a DVD release until such a time as they decide to "relaunch" the property (you know for a "new generation"). Furthermore, even if there was to be an actual "DVD release" (i.e., actual DVDs in stores), for all we know Hasbro could order such a release to be a (series of) single-disc barebones DVD(s) with only a few random episodes, and no extras. I guess what I'm trying to say is that Hasbro is now in the position to have "their" shows released on their terms and ONLY on their terms.
So for our sakes, let us hope that Hasbro will have the foresight to give these classic TV shows the treatment they rightfully deserve, not just for those older people who "were there" when these shows originally aired, but also for those younger people who might actually be interested, as well as anyone discovering these shows for the first time.
In any event, as Knightmare pointed out, the "treatment they deserve" may not be as likely if it were to be released by a bigger entertainment conglomerate. Personally I have my doubts about Shout! Factory. For BCI, I'm beginning to think that they are getting fatigued after three years of He-Man and (other) Filmation releases (OTOH, I wonder how Genius Products would handle them...). If anything, I think that Rhino should take this opportunity to at least try to get the DVD rights back (after losing them a couple years or so ago). Rhino's been good about how they've released the shows, haven't they?
