This is likely gonna end up being PS4s peak year, and i doubt next year will see a huge decline considering the games that are gonna release that year, we saw a lot of great japanese exclusives for the PS4 this first six months and im sure they are a big reason as to why it has done so well, but next year we will see some big more mainstream exclusives being released like God of War, Spiderman and hopefully Days Gone (which i hope turns out good) and obviously more Japanese games will be relaeased and im sure at least 3 of them will be great, those being Nino Kuni 2 , SOTC Remake and Trails of Cold Steel 3 which is a franchise kind of similar to the Persona games but without the reputation it has world wide.
