Why a 70% dominance of PS4 (PS2 like dominance) will be impossible

[Puppyroach]

This is pure speculation since the generation is very young. WiiU might pick up speed, it might die off. MS is already moving the baseline price for X1 and we all know how strong they are during the holidays. My guess (which probably will be wrong) is: PS4 70mn, X1 60mn and WiiU a distant third at 30mn.
