PS knows they don't need to, most people know they don't need to, but wish they would for their wallets sake. The XB1X may be a better overall value for the price of the hardware, but on all other fronts PS is at least on par if not way ahead.
With PS making a mistake on demand, and only having a minimum amount of Pro's available, this makes the cost to manufacture higher. The more parts you buy and assemble at once, the cheaper you can do it/sell it for.
XB1S has a bunch of built in hardware and software that the PS4 doesn't. Yet PS4 still outsells it 2:1 at the same price point. If XB1X was cut by $50 sometime in the new yr, I don't even know if PS would follow suit at this point.
The best I could see PS doing until a significant XB1X price drop would be a $399 Pro + new game bundle with multiple titles to choose from.
