What is the reason behind the PS4K?

[Luke888]

Because:
a)people who own PS4s might aswell buy a PS4K----->$$$ ;
b) they'll push 4KTVs and Blu Rays made by Sony (while I believe there are better 4K TVs by other companies :v)----->$$$ ;
c) Try to not become the worst console on the market when NX launches and Xbox2 occurs...
