The roc isNop, it will drop after September.
Mr Porter said that the album will probably be released after the summer.
The Grammys are - imo - one of the factors as to why we might not have an album before October 1st (and consequently the shows). Why? Pure speculation, of course, BUT, Kendrick Lamar and Eminem are both signed to Aftermath/Interscope, and one could imagine that Em doesn't want to (1) compete with Kendrick’s critically acclaimed album, or (2) "steal the show" from K dot. Depends on how you flip it, but either way, it's not an optimal situation.
Pretty sure Iovine wants to dominate 2 Grammy Awards shows instead of 1. It would be great for Interscope to win The Grammy 2014 AND 2015.
IMO, The only problem in the equation is Drake
#1 , #2 , #3 , #4 on the billboard 200 right now, I think Eminem will drop when Eminem feels like dropping. I don't think he's gonna let a grammy award to some young rapper dictate months of hectic days in his life. It's a fatter chance that he'd sign his "friends" D12 to his label.
