Kotaku - Sources: Sony Is Working On A ‘PS4.5’

[Solid-Stark]

I've been reading some comments on this.

If this holds any truth to it, I can see a PS4.5 being a new trend for consoles where a semi-successor is released every 3 years but each one is promised support for 6 years. In other words PS4.5 and PS4 will overlap from 2016 to 2019 with all games working on both, but running at full 1080p 60fps on new hardware. I'd imagine if they are similar (x86) then devs should have no issue as software would just scale. The console price range still can't do 4K 30/60fs games.

That or this new hardware is just a new drive that supports 4K BD and HDR with APU not changing, and replaces current model.
