These costumes are pretty fucking sweet. I might actually get this.

And as a bonus, the Pit fatality in MK4 is finally back. http://www.youtube.com/watch?v=ZO_AOBdy6wU&feature=mfu_in_order&list=UL
As another bonus, a sneak peak of the new challenge tower. http://www.youtube.com/watch?v=oKtwBB22P-4&feature=mfu_in_order&list=UL
You'll also have the nearly-naked Mileena from the beginning of the game. You'll unlock special costumes like the Raiden one in Challenge Tower, and as the guy in the video says, there will be a much bigger reward.
There's also rumors of klassic costumes for non-ninja characters, and the classic Cyrax and Sektor fatalities. Possibly Rain, Smoke, Noob and Ermac as well.
But with this new content comes dropped content, such as KOTH. That sucks :/
Anywho, what do you think?
