Ok this will absolutely not happen, there are no rumors, or even whispers of this - I just think it’s an interesting thought experiment.
But, can you imagine a world where Discovery sells off DC studios? There would be a bidding war, and the sale would most likely fly through anti-monopoly regulation -unlike WB in its totality.
I literally just want Universal Parks to have Batman (although I don’t think I want Universal Pictures to be in charge of the films.)
