I know were your going with this and yeah Sand buriel should squirt blood but if it really brang out the blood like getting hit by the hidden lotus or ominous chidori and has alot of detail by the damage then it will go into the 15 rated section for Violence and Blood and gore but i doubt they would just imagine Dark sector the blood and gore of that...yeah do you see my point but there should be some texture of blood in the game
As of right now ...not yet since the game does not come out until October of 2008. But soon there should be a demo being released over the summer. Also if dont have a site to pre-order you can try gamestop.
