I bit unrelated to what's going on, but something I find cool.
Someone ripped the Tekken 4 voice lines finally. There's A LOT of unused stuff. Like Hwoarang speaking in Japanese and Engrish instead of Korean, Lei Wulong speaking Japanese instead. Steve having a COMPLETELY different(and worse) voice. There's another video having the announcer listing off names the characters who didn't show up in 4. Weirdly enough, Jinpachi, a character from Tekken 5 was also named, so maybe he was intended to be in T4 at some point.
That said, all the "Hurt" grunts sound really weird when not in the context of a fight.
