@TheSonofNeptune I believe the direct quote is "I think we'll keep  Supergirl to ourselves for awhile." Meaning there's always variables and nothing is really set in stone unless Supergirl get's canceled before being tied-in the shared universe. Just look at all the leak email saying Sony denied MARVEL's request about Spider-Man, yet we are still (finally) getting Spidey in MCU.
