Johnny Cage and Kenshi accidentally got announced earlier than planned as playable fighters for MK X.
Ended up happening during GDC when the senior producer at Netherrealm Studios started to blabber a little too much when talking about the game. Warner Bros has been active getting the GDC videos of his speech removed as quickly as possible from the internet.
