I respectfully disagree. MSEP should have no more runs. It's 44 years old and in embarrassing shape. It would also be a MAJOR downgrade for DL after PTN. WDW should put it out of its misery and then it should be lovingly destroyed for limited edition pins so that it can't inflict itself on Disney Parks anymore. It was better in 1996. Now it's just sad.
I haven't heard anything yet about these rumors. Forever closing doesn't seem far-fetched, but a PTN/MSEP swap does seem very far-fetched. I can't imagine DLR would be in any hurry to give up PTN after spending so much money on it and marketing it for over a year.
