These consoles are extremely powerful relative to the PC market at a fraction of the cost. At least for the near future, they will be offering games at a locked 4k60 or upscaled 4k60 with rumors of 1440p or 1080p @ 120 for some titles. For the average consumer, who does not have a monitor or TV with a refresh rate higher than 60hz (and might not even have 4k) this is going to be at least as good or at least as useful as a $2k PC - which requires much more setup, a dedicated monitor with high refresh rate and high resolution to enjoy, driver updates and downloads, tinkering, and the like.
No one is denying that $2k PC is better. That it won't have higher framerate options, mod support, and universal m/kb. But that doesn't mean its even close to a better value for the vast majority of the market. And the new boxes are not even REMOTELY outdated when you look at the average power of PC with the data that Steam releases. If any thing they are enthusiast level quality!
Holy moley, perspective gets so skewed on boards like ours.
