I have a few questions, doesn't matter which one you pick, if any. They're very yes or no, and in a few cases, giving no answer means probably yes:
1. Will there be an option for players to play their own music in game? This was a feature in the MK9 demo that many were sad to see not make it into the full game or Injustice. Preferably something similar to Tekken Tag 2's "Tekken Tunes" menu where in you assign your own music or music from previous games to different stages that will play the music in the background automatically.
2. Is there a possibility for a team battle mode? Team battle is a mode in other fighters where in you and your opponent can select a number of characters(usually 3) and fight each other survival style, no recovering health and till the last member of one of the teams is standing.
3. How different will the different version of characters be? Should we expect a Ryu and Ken sort of difference, or is it more like Ryu and Akuma/Subzero and Cyber Subzero?
4. Are playable bosses a possibility this time around?
5. Will this game have more character customization cosmetics-wise?
6. Will Kombat Kodes make a return, and if so, can we expect more than before?
7. Will test your luck return, and if so, is it possible for an unranked online version?
8. Can we expect the challenge tower to make a return?
