According to IGN and 1up, probably even Gamespot too, too lazy to double-check, Lars is in fact Heihachi's son. He is half-Swedish and half-Japanese. Specifically, according to 1up, he is a former Tekken Force officer who is disillusioned with what Jin has done with the Mishima Zaibatsu. This particular aspect of his character isn't included in the fan translation of his profile.|
Alisa is an android made by Dr. B., modeled after his daughter. Not a big suprise there, but there it is nonetheless. That's also not in the fan translation of her profile, perhaps will be revealed during the story mode.
1up has also hinted at the possibility of Dr. B returning as a character in the console version.
