I'm assuming the Tekken leader is Aris since it shows his classic middle finger win while wearing a black t-shirt. Also the Tekken character shown was Yoshi, who he used in Tekken 5.
The Street Fighter leader is a little more obvious; Alex V. Ryu is shown and the close up of the hair cut is pretty easy to spot.
Very surprised they didn't go with Wong for team Street Fighter, but I'm sure he will be one of the 5 members. After what Aris did for the MK community early on, I hope he gets some money out of this.
