Sorry didnt see the thread here. Feel free to delete the misplaced one I made.
Anyways.... I believe Disney would sell the Alien Franchise off if it did happen. Alien does not really fit in with their other franchises. However a cameo in Guardians of the Galaxy 3 would be great if it did.
...Also they would can the Ridley Scott Prequel currently ongoing. I believe FOX might do the same too.
