It works for some things, not others. There are people who basically still don't know about Disney's ownership of the franchise. Plus, they managed to keep a steady stream of TS merchandise even before it was announced Pixar would take on the script. TS has never really left the public eye and it's only a movie franchise. Sure, the third movie and rerelease to theaters in 3-D of the first too had a hand in a lot of main store merchandising.
And I really agree that toys, books, games, stuff like that need that kind of release just before the movie. The DVD set and this recording don't sound like they need it, nor should they be subjected to that sort of wait. The DVD especially, because it really turns off collectors to have big long breaks in between seasons. Be they strategic, or based on some idiotic legal mumbo jumbo.... Look at how long it took Bullwinkle's fourth season, without any fan fare, to be released, thanks in part to the demise of Sony Wonder. And again, the DVD... we have another full season to get to. Even without Muppets Tonight, TMS complete series and single disk casual collections, and re-re-releases of the movies, they still have one season that would work perfectly.
I get strategy and I get waiting (chances are I wasn't going to get the CD anyway... I'd rather the ORIGINAL music, thank you), but 2 1/2-3+ years for a DVD release is ridiculous no matter what's going down.
