Y'know, part of the problem with the way tv shows are done here in the good ol' US of A' is that they are planned to just go on and on and on with no end in site until the ratings bottom out and it gets canceled (usually before it's wrapped up properly.) Granted there are a few exceptions but that's
generally the way it's done because we here in the capitol of capitalism have to have our ongoing franchises which can be milked indefinitely for their infinite revenue streams.
If they ditched that model and put a decent budget into one stand-alone season at a time with a story that mostly ties up at the end -- I mean really planned out a 12 episode season (or even 6 if you followed the Walking Dead model) - they could do something freaking awesome with the Rocketeer. And the show would fit perfectly with the AMC network.
Then, if it was really popular, do another season. That way they could keep the costs down for doing a show set in another time period (i.e. the 1940's).
I dunno... just thinking out loud...
But I don't disagree with you on the special edition type of treatment. It's been my complaint for the past decade that Disney has treated the Rocketeer as their red-headed stepchild. They're like the kid who takes his ball and runs home. They seem completely content to sit on it, not develop it and not let anyone else develop anything from it either. It makes no sense whatsoever.
I actually talked to Dave Stevens briefly at DragonCon probably about 6 or 7 years ago now and he said that he and Joe Johnston offered to buy the movie back from Disney so they could do a special edition dvd or even a director's cut but Disney just flat refused. Pretty sad really...
Of course I also asked Dave for a sketch but he refused.

I think I maybe didn't make it clear I just wanted one of those little thumbnail sketches he used to do and that I didn't mean a full blown convention-style drawing. He said he did do commissions (which probably would have cost a couple of thousand I'd guess)... boy do I regret not taking him up on that now.
