Why Sony can't just let God Of War die and move on?

Have you got news of a PS4 GOW game? If not, this is pretty odd timing and a weird belated reaction to GOW3.

I hear GoW Ascension story mode was pretty disappointing in the plot department.

OT:  Do we know for sure that it's SONY pushing for these games rather than SMS actually wanting to make them?
