^ Nah I don't think so man because, Recovery was the cap-off to that I think.
He's already talked about his post druggy life for two albums now.
Relapse may of been a stylistic / conceptual relapse, in terms of... poking fun at himself, and being over the top shocking etc. but, it still involved that stuff, as subject-matter.
And Recovery, was him - recovered. Him in a new, clear mind-state. To try and drag that out for ANOTHER album now would seem redundant.
Now is the perfect time for him to break free of his 'storyline' of albums. Every next album has followed on from the last now, in this chronological, conceptual line. But now that he's Recovered, he's reborn, artistically and can go anywhere.
To try and take another storyline step, 'further the Eminem story' at this point I think would be a major-failure on his part. A failure to evolve and seize this fresh start.
