I think the first European leg will be Revel Reloaded, with Grown Woman, Bow Down and maybe another new track. (It will still be an incredible show)
The single will come in May, and album in June. She will tour and promote the US with a revamped setlist with new music and then the rest of the world (South America, Aus, Asia and maybe SA if they think the demand is there)
She will then do a second European leg as the Pepsi competition indicates, with new music giving fans who desperately want to hear the new songs live or who missed out the first time, a chance to go (maybe some European stadiums such as the Aviva and the Amsterdam ArenA)
Of course this is just my theory which will probably go nothing to plan and Bey will make it complicated and messy
