Wrath: Aeon of Ruin has come about via some old classical inspiration. If you liked Quake, DOOM, Hexen or the like, then you're going to love this as it blasts onto Xbox, PlayStation and Nintendo Switch.

It would be kind of funny if this is true as a whole press conference was based around this feature and Sony have stayed silent on the matter as if its only vaguely important (it really is imo). I think the most intuitive way to browse the menus and UI could end up being the touch pad. If not though, analog sticks have never failed me.
Any new features is a bonus for the PS4. This feature is not one I would use myself but it could be cool for Netflix or something to navigate the browse page.
