That's correct, there doesn't seem to be 100% official confirmation that the Arcade Collection is getting JP ROMs. I saw someone say Konami EU confirmed it, but haven't seen any sources (and the fact no other branch has spoken about it makes me doubt as well).
All we know is the Castlevania and Contra ones are getting the treatment. The tate patch for Arcade was actually a surprise AFAIK.
