It looks like Mortal Kombat X will getting another four DLC characters, the first of which may be revealed tomorrow.
Earlier today, the game's creative director Ed Boon tweeted an image of four silhouetted characters accompanied by the game's logo and the words "Who's Next?". Boon's caption simply says "Tomorrow?", teasing the reveal of a second round of DLC characters and, perhaps, the announcement of one (or more!) of who they'll be.

Mortal Kombat X already has four DLC characters - Tanya, Tremor, Jason Voorhees, and Predator - who were bundled together in the Kombat Pack season pass. In a live stream showing off Tremor back in July, NetherRealm referred to this as "Kombat Pack 1", indicating that there could be a second round of DLC characters.
Nothing has been officially announced at this stage, but between the "Kombat Pack 1" comment and Boon's latest tease, it looks like that there will be a Kombat Pack 2.
