Considering WB announced their plan of focusing on live service games, I just don't see them doing Shaolin Monks style game at this time. Though I would love to see it.
I think they go for Injustice 3 or a comparable DC fighter. It appears that they cut development on that to switch to MK1 so I figure they will try to finish what they started. Both games were very successful.
But at the same time, WB also announced that they will focus on certain franchises and mentioned MK, and I believe MK is a way bigger seller than Injustice was. So maybe they will just go into MK2. It's the safest option for them, and even with the criticism, MK1 did pretty well.
