What exactly is Prince up to?

Fans have been wondering for nearly two months, since he suddenly started releasing new songs and videos on his website, then made appearances on "Late Night with Jimmy Fallon" and the Grammys. Some answers started to come into focus on the last night of SXSW, as Prince delivered a jaw-dropping performance with his new 22-piece band at a party thrown by Samsung Galaxy to promote the new smartphone. Prince lived up to his reputation as one of the best performers alive with a 2 1/2 hour set that included a few hits, but mostly focused on extended funk jams. There are rumors of a world tour and a new album, but for now, his next move remains a mystery.
