Also... this is a business lesson. Sony really hasn't had a killer/system selling MP exclusive game (closest would have to data back to SOCOM).
They have been overly dependent on multiplat games along with their brand loyalty and install base to fill that void. MS has always had HUGE cultural MP games since it's existence (Halo and Gears along with everything else that other developers made turned the Xbox into the competitive console of choice). This is kind of like Netflix after they really started gaining momentum. The landscape was changing... and they saw that they were too dependent on licensing IP from other studios and companies. As a result they started investing in content and building out their catalog... now when you scroll through Netflix, SOOOOOO much of it is their own shyt. The old way was not sustainable... Also since they were first to market, even with all the competition that spawned since they came out, Netflix is still the most recognizable one with the most users.
Sony has a great catalog, but they rested on continuing to do what they've been good at opposed to adapting to where the comp is going all in at. They should have had a legit competitive MP game by now that people care about in the eSports lane, or like people cared about Halo and Gears that really carried MS for a decade.
Now you look up, and Sony realizes that they MS is building up competitive advantages that is going to be hard to keep up with. MS is the plug too to much shyt in this space, from development, to software, to cloud services, you can't escape them.
