Well, looks like the album cover is official because it's now posted on U2.com.
They've also confirmed all of the details (the everyone seemed to already know).
The only thing that's a little disconcerting is that I don't think the Bonus track will be offered in the Box Set.
I think downloading it or buying the japanese/(UK?) versions will be the only way to get it.
