Saw the video yesterday, he makes a compelling case.
Tl;dw Main Factors:
1) When Comcast renewed the deal in 2019, they owned the Jay Ward IPs, so there was potential corporate synergy with new projects. That's gone now.
2) Assuming LC work begins this year or next, should be done around 29-30. Right when the TL contracts are up. And it doesn't seem likely we'll see major overhauls to Potter, JP, Marvel, Kong or Seuss anytime soon. That basically means IoA would remain stagnant throughout the 2030s. Possible, but probably not desirable given you could give the Hogsmeade treatment to a new IP (maybe even two) in that space.
If it happens, I do hope the rides are just re-skinned. And maybe USO and EU need so much help they can afford to let IoA ride after LC's replacement. But I'm sure it's something corporate is looking at closely between now and 2029.
