DVD sets from 80's and 90's cartoons are coming along pretty quickly.
DiC just made a new deal to put out some more sets, starting with a Heathcliff & the Cadillac Cats boxset, followed shortly by Inspector Gadget, Sabrina the Animated Series, and collector's editions of The Legend of Zelda and The Super Mario Bros. Super Show.
Warner Brothers has been doing pretty good, releasing the Paul Dini / Bruce Timm Batman and Superman series as boxsets. I still haven't heard about any Batman Beyond boxset though. (I imagine they'll get to that once they finish up with the other Batman boxsets.) They're also putting out a boxset of Thundercats (season 1 part 1) very soon!!! They've been putting out single disc DVD's of all sorts of shows including A Pup Named Scooby Doo and their current shows like Justice League, Teen Titans, The Batman, etc.
He-Man's coming, starting with a two disc "best-of" set, followed by complete season boxsets some months later. The group that got those rights is also putting out the Fat Albert cartoons, and has the rights to She-Ra, Casper the Friendly Ghost, Felix the Cat, and Ghostbusters (don't know if it is the one based on the movie or the one with the monkey).
Count Duckula will be out soon, along with Danger Mouse!!!
Jem's out on DVD. Transformers and GI Joe have been released.
Go-Bots... Now there's a sticky one. Neither Tonka nor Hanna-Barbara own the characters anymore. Hasbro sued them for "copying" the Transformers and either won the suit or bought the characters as a settlement (I've seen it reported both ways), hence why the line of Playschool Transformers are called Go-Bots, and why so many of the old Go-Bots character names became Transformers Minicons. I haven't been able to find any information on what will ever happen to the old Go-Bots cartoons. Hopefuly something will be worked out eventualy.
