Michael never said he wouldn't tour ever again, not recently anyway. Dr. Tohme is Michael's spokeperson and it's nothing but pure speculation and opinion that he doesn't have Michael's best interests at heart. He's doing a job, like he's supposed to do, and so far, he's done a good job. And Michael has told several fans in Vegas and LA that he IS planning on touring. This just comes as an official statement.
Why even harp on that though? Michael's healthy, and that's all that matters, and him wanting to do everything outlined in the statement is a bonus and should be appreciated and met with excitement and appreciation rather then skepticism.
