Sony should really put more focus on the SW bundle. 1 $300 PS4 bundle against several X1 bundles of the same price is a tough battle for Sony.
There aren't going to be several X1 bundles at 300, just Gears. The others will be reduced too but they're more expensive to begin with, so they'll be 350, 400 and 450. But yes, they should do that with the standard SW bundle.
