The PlayStation 4 Pro marks a turning point for the modern console era. In fact, it redefines what a "console" even means. Consoles are supposed to offer "good enough" graphics at an attractive price point, and a consistent hardware target to allow developers to optimize the crap out of their games. Meanwhile, PC gamers can spend twice as much (or more) and get marginally better graphics and all the headaches and complexities of playing games on a grab bag of hardware.But the PS4 Pro is a mid-generation spec upgrade to an already successful console. It adds power and complexity to the console equation, at a reasonable price: $399, $100 more than the slimmer version of the original (and less powerful) PS4. The extra expense also gets you a nice big 1TB hard drive, an extra USB plug, and optical audio out.
You can debate the fittingness of a "Pro" moniker on a piece of hardware designed to play video games better, but Sony really has made this new console a notable improvement over its standard model.
