"Sony is totally going to sell their thing at a loss."

The PS4 was underpowered at launch and has been profitable for a while now I believe. The Vita was originally sold at a high as fuck price with the memory cards also being expensive as fuck.
Being good at business isn't a sin or a bad thing necessarily, but fanboys are spinning a really dumb narrative. Sony wants to make money at this point, while taking very little risk.
PSVR will either be okay at best quality wise and still be sold for $299 or $399. Or it'll try to match the Rift and be sold for $499 or $599. Sony will not release a magical product that's better than the Oculus Rift while eating the cost. They're going to test the waters with a inferior but more cost effective product or exploit the nerds with expensive tech, its one or the other.
