That's the entire point though:
Capcom's software pipeline is supported primarily by the PS4 and with RE, DMC, MH all breaking records Capcom are going to double down on the PS5. Same with SE, FF7R2, FF16, Project Athia, KH4, Nier are all going to be on PS5 and not SW, resulting in SE being heavily dependent on PS5.
The initial post was making a statement on JP third party software support by using JP sales. This has proven to be a poor inidication, as I have mentioned prior, most JP pubs get most of their sales overseas and so JP third software pipeline is decided on overseas sales rather than domestic.
PS4's software sales absolutely dominate SW worldwide. Granblue Fantasy is not Japanese centric, most of its sales will be overseas.
I dont really agree or disagree with a lot of what you say, but Granblue fantasy is absolutely Japanese centric. Youre referring to a game that is based off of one of the top 10 mobile games app in Japan which makes it a huge money maker. It doesnt even have an international release. Even if the console game does manage to sell more overseas than in Japan, it certainly will have an abnormal sales ratio between Japan and the rest of the world
