So you agree it's not going to be the focus, which is what I said. A PS4 show. I doubt they'll show much or any focus on a Japanese PS3 game when their main focus will be selling units of their new console to their western audience.
It's like me trying to get hype for a new Tales of Zestria trailer tomorrow.
I don't think almost anyone is doing that for P5. The most I see people thinking has a good chance of happening is a mention or short part in the inevitable PS3 montage (of the reveal trailer, of course).
