I think that Kung Lao will be available somehow as a playable character for 1 reason. If you go to the photo section of the Kontent area and look up the picture of Luis Mangubat....it says:
"Luis Mangubat - Character Artist - Luis created new designs for many returning MK characters including: Scorpion, Sub-Zero, Kung Lao and Raiden. He also designed Shujinko and the Dragon King."
So I am sure that he will be an unlockable....It is possible that the Kung Lao design he did was just for Konquest mode but, hell, if the other 5 people he designed are playable....why not make Kung Lao playable?
Anyway....what do y'all think?
