Sadly, Tony's days of creating new lands/attractions are over at Disney (unless some key folks get fired).
The only reason that Tony agreed into being forced into retirement was the slim chance that he could be involved on another project.
Obviously, had Tony's . . . "retirement" been under friendly circumstances there would have been major events related to this event, such as special recognition for Tony's long service to the company. He was pushed out the door, there isn't a nice way to sugar coat it.
Tony was all for quality attractions, and had he been in charge of new attractions like Monsters Inc., Mermaid, they'd be closer to the quality of Carsland versus the cheap/clueless attractions they are which obviously weren't supervised by somebody with the good eye that Tony has.
