Found it on gaf
Senran Kagura 2 Shinku is for the 3DS, and it'll come out on 8/7. It'll have 2 new male characters. Sidescrolling game, but with 3D fields for the bosses.
Dekamori Senran Kagura is "hyper big-breasted cooking-rhythm game" game for the Vita, coming out on 3/20 (DL-only). If you lose, your characters is stripped. The game will include both sets of ninjas from Senran Kagura Burst and will cost 2,400 yen. Other characters who appeared in Senran Kagura: Shinovi Versus will be added as DLC for 2,500 yen on 4/24/14
There's also a 3rd game for a Sony console, called Senran Kagura EV, and which is apparently related to Shinovi Versus.
They were supposed to be revealed via a Marvelous AQL 's Senran Kagura livestream tomorrow
