Part of Xrd's case is bad/lazy programming, basically, PS3 shortcoming and them not willing to fix the stuff for the PS4 version. Character in Xrd have a huge library of VA, so big, they can't load the whole library at once on PS3, so what they do is they switch between VA libraries between matches(which I assume is part of why the game goes back to the loading screen while restarting).
For example, I-No will say "Marry Christmas" every single time during the same match when firing her note projectile, in another match the game will load another sentence for that move and keep using it, you'd never hear her say "Marry Christmas" no matter how many times you use the move. This was obviously due to lack of enough ram on PS3, but the same problem carrying over to the PS4 makes no sense at all, they just didn't bother fixing it.
