With only 20 hours left in Ed Boon's countdown it appears that Amazon UK has listed "Mortal Kombat X" on it's store
The game is listed to be available for the PS4, PS3, Xbox One, Xbox 360 and PC. The game was also given a release date of 2015, which fits NetherRealm's previous games schedules to announce at E3 and then release the following spring.
If "Mortal Kombat X" is actually the shipping title, and not just the code name, then I anticipate that the X in the title is not to be officially pronounced "Ten" but rather the letter "X" and may be tied to the story line of the game. It would be confusing to most people to call the game Ten since the next game would be a sequel to 2011's Mortal Kombat.
Stay tuned because Kombat Kontinues tomorrow at 8am Central Time! Are you ready?
