In my eyes,
, does not at all disprove the Gardevoir leak. Here's why:
Yes, he says the leaker had the wrong Castlevania character, but he wouldn't know any insider information at all if his story is true. If he only saw Richter's name then it's a clear assumption for him that Richter was chosen OVER Simon. Why was Simon not listed if Richter was?? Couldn't tell ya, but no one here knows how demo porting process works well enough to know why he wasn't either. Maybe Richter's move-set was finalized before Simon (note: NOT character choice, but animations or design aspects), and they used an earlier build for the demo. Maybe during that build in development time, Simon wasn't working properly so they completely took him out of the code to work on, and/or to just remove since that demo was just a throwaway build and not something to be worked upon. Maybe this is all nonsense a bored kid guessed on 4chan and happened to get some things correct.
I personally don't want it to be true, but the point is, we don't have enough evidence to disprove this leak as of now.
