if you have a ps 3 you can be happy, cause soon there will be tekken 6 and with 41 new characters (even the ones from dark ressurection from psp expect for Jinpachi Mishima)
6 of the new chars:

Leo-a german boy 19 ears old that uses the Hakkyoku-Ken fighting style
Miguel Caballero Rojo-it's a 26 ears old spaniard that speaks english and escaped from home at the age of 15
Zafina-no description
Azazel (final boss)-no description
NANCY-MI847J- it's one of the bosses, has the life bar 6 times longer than a normal tekken char. and can fire lasers that brake the flor, it means game over for you if you fall down.
