My views are quite simple: Eminem always makes albums in pairs. SSLP vs MMLP, TES vs Encore, Relapse vs Recovery. MMLP2 vs ???
I have 2 guesses, either MMLP3 or TES2. Just to pair off MMLP2. He will then release his very final album and that will be a "pair" to Infinite. My guess would be the exact opposite; Finite or Emfinite or something like that.
No doubt we have a couple of years to debate this so I'm sure someone will guess the correct title!
