Why does it need to be patched? It had that patch shortly after it came out to fix the save glitch

ORAS is getting a bunch of new Megas. Unfortunately, you can't access these new Megas or primal evos in XY. It's still compatible though.

I get why customization won't be in ORAS, you're playing as remade versions of the ruby/sapphire protagonists while in X/Y you're playing as whoever you want to be. I'd like unlockable classic outfits in ORAS though, that'd be cool. Don't like May's new clothes.
