The wait for this, and then the wait for the disc release, will be unbelievably painful.
Well, it'd be more someone inserting the line onto a photo of the real cover (Madoka getting another cover would be pretty unsurprising). Basically, the suspicion was that it's all legit except that one line. I'd put odds on it being legit too but would rather be skeptical until they confirm it.
So HMV initially said it wasn't legit ans that Nanoha was on the cover, then retracted that tweet, then someone else tweeted it was and... 2-3 days until we know for sure.
