In the end, they all want to be like Apple. And I can understand that Sony thinks they are currently Apple in the console market. Big and loyal fanbase, market leader, good reception, good image, big sales, momentum.
Everyone wants to be that. But if you look at the declining sales development of Apple's tablets, this approach might (!) have a negative impact on Sony's console sales on the long run.
Because, at some point, diminishing returns will make people ask themselves why on earth they really need the newest console. Traditional gaming is already affected, some people can't even tell the difference between an old generation game like GoW3 and and a current generation game like Quantum Break (yes, pun intended). (PS)VR will heavily profit from faster hardware, so this might convince people to upgrade to the newer SKU. But at the end of the day, I have no doubt that only exclusive, hence not "forward compatible" games like a new GTA or Uncharted will convince people to upgrade, while others will keep their old one.
So, at the end of the day, you split your customers into separate bases with this approach, and I am not sure if that's a good thing on the long run.
