My prediction is Eminem will try to emulate MMLP but will mostly come off as Recovery era Em to the listeners and even if the album is really solid or on par with Recovery, the critics will have a field day with it because of: what "The Marshall Mathers LP 2" seemingly promises and: what we get.
The songs with pop features need to deliver big time to redeem themselves on an album which is supposed to be the sequel/revisit to the original MMLP.
Don't like the fact that Kendrick Lamar is on there, probably a label move, but since people like him so much, it's alright I guess and hopefully Eminem murks the kid..
Also, don't forget, the Activision press release explicitly stated there's an exclusive studio track on the COD edition in addition to Survival, plus probably 2/3 iTunes Deluxe Edition tracks. They might also release a physical deluxe edition as well, who knows..
