Been digging a "leak" from 2017 coming from Reddit and trying to compare with this "leak", not that one will legitimate another somehow, but it's fun to see what people make up to look real.
Of the things usually repeated, bigger roster, longer story mode, returning characters and Raiden as someone to be beaten. In other words, things everyone could come up with.
Funny thing is that they usually point Daegon and Kano's son, of course things coming out of endings. This 2017's one also speaks how they would deal a little bit of what was between Deception and Armageddon in the original tl.
Oh, and there was something about a lady that could make weapons out of thoughts lol
