I'd say only 12 left. The open slot in bottom right will likely be left for dlc. I wish NRS could put together a better looking roster layout though for when dlc is added. MK9 dlc screen was just odd.
Doubt Jade or Noob make it back. Could certainly do without Shang, Mileena, Nightwolf, Sindel, Rain, and Kang (unless zombee Kang is back).
Hoping for
1) Cyrax/Sektor/Smoke variation cyborg - Make it happen nrs
2) Tremor - Waiting forever on this
3) Hotaru - Unique
4) Havok - Just so b.a.
5) Moloch - Need another big
6) Tanya - This is almost guaranteed
7) Reiko - Also b.a.
8) Fujin - Can do some cool wind stuff
9) Kenshi - Need anti zoner
Next two are pretty much given
10) Shinnok - Duh
11) Goro - In already
Leaving last slot for someone new or guest slot
12) tbd
