In MKX I was a bit disappointed that Liu and Kitana are in, despite minor story role, however in this game I just can't wait to see them back! And I really hope Liu will get his redemption and will be the MK champion again!
On the Kotal Kahn part... it's not surprising that much that he lost to Shao, who was brought back in great shape. But hopefully we won't see any abominations as his fight with Kung Jin. Kotal needs to shine!!
