He talks about going back to his "first love", but nowhere in here does he say that he's working on Detox. He even says, when asked whether or not the material is going to be thrown away, that it'll be there for whoever can use it. Also, that he's not recording for any specific reason, but just to do it because he loves to.
So, yeah...any blogs or hopeful fans that characterize this as a statement about him working on Detox isn't reading it carefully enough.
