The revived Kages will be playable characters in STORM 3

[Susano'o the Storm God]

However, pressing the snake into a corner isn’t wise as Kabuto bares his fangs, summoning the most fearsome ninjas from ages past, including the previous Raikage, Kazekage, and Tsuchikage, as well as the Seven Swordsmen of the Mist. With the war quickly spiraling out of control, it’s up to you to take control of the battlefield as the Storm continues to grow!

Taken straight from the advertisement description for the set, heavily implying the kages will be in this set. For some reason though, the Mizukage is strangely missing...
They will probably be void and have sacrifice, but I would also like versions of the kages with what their normal elements would be w/o sacrifice eventually >.>
