Question on the roster. (Mortal Kombat 11)

Hello. I understand official information where there is none, and hardly anyone will say. But maybe You have assumptions. I wonder what happened to the 11 MK kun Jin, Takeda? They are for the second run? No mention that they will be in the roster, though as I recall their story arc in MKX is not over. Concerning them, do not quite understand why introduce characters, write a story and the next part to forget about them as if they did not exist. I hope that in the story we somehow explain their absence. Also concerned about the lack Ermaka, Reptile, Kenshi, Fera tor, TRIBOL.
