Actually, every player has been aware that the switch version is the weakest again. I personally have no interest in old (remastered-)games, 2018 will see an incredible number of new AAA-games and blockbusters. A Dark Souls 4 would eventually appear only on PS4 / xone, but a new part will not come in the next few years, said the developer.
The souls-base is very huge on PS4, especially the online-player & psn-communitys. 2019 then Bloodborne 2 for all Souls-lovers/fans, I'm sure.
I wouldnt be so sure.If Dark Souls remaster ends up selling well on the Switch, which I feel it will be the best selling version, Bandai may very well consider making a version of Dark Souls 4 on Switch.Hell, for Japan alone that port may be worth it.Graphics are getting less and less important and assuming the game plays as well as the other versions and it will have overall enhanced assets on the Switrch, even if not in the same level as the other versions, people will be more than fine with it.Ever since From Software appeared as a supporting developer for the Switch, gamers have been eargerly awaiting for this game on the Switch.
Not that Dark Souls 4 will happen anyday soon anyways....
