Software wise its looking really bad in Japan but we dont really know for sure because of digital. If we look at the 3 PS5 exclusives, Returnal, Ratchet and Demon Souls, all selling around 20k in Japan but worldwide they are doing well over 1 million
Returnal didn't sell over a million though, at least yet.
It's definitely a combination of different factors. Digital share, scalping etc. But it still looks terrible. My bet is that at least 300k consoles have been sold abroad.
Considering RE8's digital share wasn't high I think we can rule out digital in general being over 50%. Afaik used game sales didn't grow either.
