DC may have lost the rights to the Milestone cast
When asked whether there was a chance of seeing Static Shock in "Teen Titans,” Lobdell replied, “Nothing would make me happier.” However, he said "legal issues" prevent the characters from joining the title.Does this mean they no longer own the rights to the Milestone line originally formed by the late Dwayne McDuffie? Well, it's doubtlessly for the best, because attempts to integrate them into the DCU were disastrous from the beginning, and they clearly had no idea what to do with them, in sharp contrast to the Charlton characters they'd added in the mid-80s (Blue Beetle, the Question) whom they were much more successful with. They weren't very respectable of the Milestone heroes either, seeing how they ended up treating Static Shock in his last appearance to date. And they don't seem to know what to do with the Wildstorm cast they've shoehorned into the DCU proper either.
So if the rights to Milestone reverted back to McDuffie's heirs, I'd say that's a good thing, both for the characters and the heirs too. They could now take them to another publisher like IDW or Dark Horse and find writers who could manage the material much better than the editors dominating DC today ever could.
