AT&T can't be that crazy to give up those IPs can they? No one is willing to just buy the publishing side and still pay AT&T for licensure.
I'm really just basing that on 1) Warners always having treated DC like a redheaded stepchild ever since they purchased them and 2), as Torgo said above, AT&T having a history of shortsighted and often illogical moves as a corporation.
Like if you just compare the place DC occupies with Warner Bros. and how they are treated there vs the place Marvel occupies with Disney and how they have been treated there it's a total Goofus and Gallant thing. Warner Bros. purchased DC in 1989, and in that time the only IP in their portfolio they've consistently been able to leverage is Batman despite having the most well known and oldest characters in the superhero genre. Even when they stumble backwards into a breakout character (Harley Quinn, for example) they end up sticking in her in a garbage movie that bombs completely in Birds of Prey.
Meanwhile Marvel/Disney turned Groot, a C-lister alien tree, into a household name. They've turned characters no one outside of hardcore comics fans knew into billion dollar film franchises.
Even before the AT&T purchase, Warner Bros. was really bad about understanding the value of what they have. Now that they've got an even more mercurial parent company to answer to, I legitimately have no idea what might happen.
