Last I heard Obs owns the IP, but it was secondhand info IIRC.
As things are going now, if I were Obsidian, I would release it DD only, in a non-crowded month and rely on word of mouth.
Not that they could, with SEGA(most likely) owning the IP. I think some game developer said that the first thing to do was to make sure that you own the IP and not the publisher.
Also it wouldn't work too well with the whole multiplatform thing.
Also, where is the link to the big SEGA announcement that AP is delayed indefinitely? And no, 8 different dates and publisher silence isn't an indefinite delay.
