You are really giving the licensing fees from games sold too much credit. The install base will be too small to make up for any initial losses on the HW. They take in like $7 per game sold so each $100 off the top would need to be made up by 10 game sales. With this small of an install base plus the R&D baked into the HW they are not going to take a bath on the HW. Sony is playing by the same rules as their competitors in regards to the components of their hardware. Its small production runs for this stuff which will be expensive.
Many mistakes that I see here.
1) the fee is generally around $10 afaik. Probably make more on digital games.
2) they have no competition on PS4 for VR or sales portal, so EVERY VR game sold on PS4 is not just sold on their VR platform but also on their portal. Not so for HTC or Occulus.
3) Sony is a huge consumer of OLED screens. Only HTC compares in that regard, and then they are the only ones that combine proprietary camera sold as accessory for years, proprietary and lone sales portal, and sole VR headset on their market that is nearing 40m units of VR capable units sold.
4) Sony is a large maker of consumer electronics (HTC being again the closest example), with longtime experience in creating customer devices in terms of design/ comfort, and large scale manufacturing. They also have a tremendous amount of experience and capability in designing cameras and optics/ lenses.
5) Sony has already every unit (PS4) VR ready, with a VR controller (DS4) included and with Cameras widely available separately to split the cost ahead of time.
They are anything but playing by the same rules imo. But we'll see, hopefully within 2 months.
