It's also perfectly reasonable that they knew exactly when the PS5 was due out and planned accordingly. This is a Sony first party studio we're talking about.Well It is perfectly reasonable that they started production on ps4.
Cool. Can you point the rest of it to it so we can see for ourselves? "Basically" suggests that there's some nuance going on there. Translator-san does a great job but he does sometimes skip over detail for the sake of brevity....not an insider lol, Kazunori basically said it by himself in one of the tech previews.
