I think he'll do a milli first week.
People underestimate how many new fans he picked up with Relapse and Recovery and how many old fans he awakened. We've all followed him regardless because we're obsessed but the amount of people I see like... ranging from young kids to middle-aged women

who'd never heard Eminem prior to Relapse even is amazing. Then, the amount of people he connected with Recovery? with those monster hits etc. forget about it, he sold over 600k after being in a cave for 4 years, then nearing 800k with the next one... there's been a bit of a wait for this one, if the single is big = 1 mil first week.
As for worldwide sales... hmm, I reckon 5 mil in the US, 10/11 worldwide. It all depends on what momentum he creates with the theme, which to be honest - I am itching to see... I am so interested as to what fucking theme, title and imagery he's going to hang this album off... because he's uptodate with his life material and given the way he evolved with things like "Love the Way You Lie", I just can't see him looking backwards and using his childhood or anything, so, I'm intrigued. What's he gonna do...
Also, we know he's gonna sell at least 600k first week, which is pretty fucking amazing. No other artist in history, to my recollection - has maintained the momentum he has. You have like Lil Wayne who sold like a mill first week with C3 and again nearly a mill with C4 right? but his first albums didn't sell like that, it's a momentum he built over a long time with an abundance of material and not all his shit sells like that. Where as Em debuted with like 270k or whatever and then 1.7mil, 1 mil, nearly a mil with Encore?, 600-odd, 700k-odd... I mean, his momentum has been sky-high for like 13 years, that's amazing and if sells near a mill this far into his career, despite already being well past creating his big impact... that's unheard of. Either way, I just hope it's a fucking classic. Sick of them being just short now, he's had 3 bad-decent albums in a row, make a classic Em!
