idk i have heard 2 i have heard more then two i heard 1....ign said SECRET CHARACTERS 'MAYBE' but i guess other people assume they need to say how many will be in the game i*for one have seen all the pictures all the interviews and all trailers and*dont really*know how many secret characters there are*
there are no confirmed characters besides the characters in the official trailers
but i doubt zabuza and kankuro would be secret.....kankuro sucks....and zabuza...just isnt a secret type of character to me a secret would be like azuma or itachi and kisame ya know...someone unexpected zabuza is the first bad guy that would make no sence
no i mean its a character based on secretivity....like say kimimaru! if the sound 5 arent going to be in the game everyone's like "aww crud this sucks so bad" but then they whip out kimimaru and every sound 5 fanboys like "omfg its a sound ninja!"
