Why is Resident Evil Village PS4 promo disc so rare?

[DoctorKong]

Hello, I recently discovered that the PS4 promo disc of Resident Evil Village is pretty hard to find.

Just few copies around. I asked people who worked for websites and they told me that Capcom mostly sent codes for downloading the PS5 or XBOX Series X version to journalists so the PS4 version was a bit "forgotten". No one of them received a copy for reviewing PS4 version.

Do you think it's a low press promo disc?
I think that in few years it will become highly collectable due to the fact that promo disc are something "of the past" since now publishers just send download codes
