Why hasn't SE released FFX/X-2 sales info yet?

[Sora96]

We know Final Fantasy VII has sold over 11 million copies, Final Fantasy VIII has sold over 8.5 million copies and Final Fantasy XIII has sold 6.6 million with Final Fantasy XIII-2 on 3.1 million before Steam and mobile sales. But Square Enix still hasn't released sales information for Final Fantasy X or Final Fantasy X-2 despite the HD Remaster which we know for a fact sold like crazy, selling over 500,000 copies in Japan alone on PS3/Vita.

Well, I don't think it has anything to do with the sales figures being low, but maybe they just haven't reached a quota yet? It would be a silly thing, but it is odd that the sales info hasn't been released. :|
