I think there will be at least three singles: LAST MAN STANDING, THIEF OF HEARTS and one of the most successful classics: LIVIN' ON A PRAYER, IT'S MY LIFE or ALWAYS (in they'll include this), do you agree?
Like we saw with Crossroad, the inedit songs are usally released as singles, especially if one of these have a guest in it.
Finally, I doubt they'll include any cover in the album, because they didn't announce it like LMS and TOH. But never say never! I'll always hope until the release of the tracklist in the inclusion of Heroes!
