I think people are completely missing the point about Andrew House's comment concerning the PSVR, and forgetting Sony have always said this. Sony are not going to market this as a peripheral but rather a product in its own right. They're not going to expect PSVR to sell PS4s, they're expecting PSVR to sell to existing PS4 owners. It's easy to understand the difference between marketing it as a product in its own right and a peripheral, one only has to think of other products that require other devices in order to function as expected. Take Blu-ray players for instance. When was the last time you saw an advert concerning Blu-ray that ended with 'TV not included'? Just think about that and you'll fully understand what Sony are doing here.
It's not about PSVR becoming a huge success, it's about PSVR becoming a viable financial investment that has enough content to sustain it over the years. Who knows, perhaps it will become a huge success but that isn't Sony's priority at launch or in the near future.
The PS5 Exists.
