I know that the Japan version has said +1, but I'm still quite convinced that there will be something special about the Japan one. Mostly because bands release a different version in Japan (mostly with more songs) due to that japanese people won't import the album from elsewhere which is usually a little bit cheaper. So my guess is that if the songs are the same number as the European one, it will be a different song.

But we'll just have to wait and see. I don't think the tracklists for the different versions are that far away..
