He had this weird quote on Scott Souza's blog:
“I’m not allowed to discuss the progress anymore. Only just, like, where I’m at right now. I worked out today and it feels good.”
This makes me think either they think he is going to be back at some point, but they don't want to let the press know until they are more sure...or much more likely, they are planning on shutting him down completely, but don't want to announce it until they are positive.
