The very first bikini trailer for Dead or Alive 5 featuring some of the bunny outfits for the girls available as pre-order bonuses from Amazon (black ones) and Gamestop (white). The video shows Kasumi, Ayane and Hitomi fighting it off and showing some moves, stuns and juggles. No new characters were revealed though.
There's another one with Leifang instead of Ayane but the voices in that one are in English. Terrible. But I'll be sharing it in a big anyway.
