A lot of justified skepticism.
But it looks to me they took the MK:XL and Injustice PC release, meaning they are only gonna release the complete edition of the game on PC. In that case, I think there is a good chance of an acceptably good PC port
As far as I remember, Mortal Kombat XL plays well on PC, and actually broke the one-million sales milestone (haven't tried the online portion though, but they said the netcode was completely overhauled when they released XL)
Edit: Injstice sold more than one million as well, so I think a PC release eventually makes sense.
