Is this going to be a clear one sided generation for the PS4?

Seeing it dominate +70% in many markets already, at current price and with the library being what it is.

It will only dominate even more later on, just imagine European sales when its price hits half of what it is now and with GT MGS Uncharted FF15 GTA out on it.  Maybe 90% market share.
