Two words: Asheron's Call. Never say never.
Well, that's a different kettle of fish altogether though. Turbine self-publishes. Asheron's Call 2 was their game. They decided to bring it back. There was no Psychotic Korean Overlord Who Owns the IP in the mix.
Sorry, not being negative, just honest.
Lots of other games have been rezzed, but none with the particular circumstances we've got. Pirates of the Burning Sea just went indie, but they were with SOE, one of the more gracious of the NA publishers out there, who parted ways and let them sail off into the sunset peacefully.
Hellgate: London was rezzed after a miserably buggy launch, but when its devs, Flagship Studios, went bankrupt, it was actually the bank they still owed millions to who seized that IP (as well as Mythos, the dungeon crawler Flagship was making) and hired a whole dev team to finish and re-release it (and Mythos).
A.P.B. was rezzed, but it was bought out after its original team went bankrupt; I'd venture to guess its assets were sold off to try and settle some of its original debts.
This is the fate that will befall the never-released Copernicus before long as well, as Rhode Island tries to recover some of that 75 million in debt that's been forced onto its residents.
I guess the thing we *really* should be hoping for is that NCSoft goes bust. That's about the best shot we have to ever get the CoH IP sold.
