I'm looking forward to IJ3 if they expand the roster. Personally, I don't like the multiverses concept, but since they went that route. I think it would be where there is an ultimate battle of the multiverse. This way we won't just have a tyrannical Superman/Injustice Lords. With the extensions they are giving MK11. I think we can see a storyline that last 8 hrs or more of gameplay. I hope for the gear system to return with expansions of gear, exchangable abilities, skins, shaders and etc. I would like for them to add different supermoves that you would also to be able to exchange. I have a pretty huge character wishlist which I really hope they would take seriously and make it happen. Since MK has been a bit downgraded to the amount of fan fav characters that haven't returned or aren't returning.

I don't really want any guest characters unless they would bring back TMNT with Shredder and/or Hellboy/Abe Sapien/Liz. I really like the first two rosters and would like majority to return. Including some new comers of the DC Universe. Then we can get skins against like for Green Lantern, Flash and Aquaman. I think the different characters that are Green Lantern, Reverse Flash/Zoom/Savitar/Godspeed/Jay Garrick, Ocean Master, Powergirl and Big Barda. Would be pretty cool. I know that is an extensive list but they have done that many characters for MKA. So why not hope for IJ3.
