I think Sony made the right decision going for a truly top quality device instead of entry- to midlevel VR for maybe 200 bucks less. Of course I would also have liked a lower price but it's already amazing that the VR2 apparently surpasses top end PCVR headsets costing far more, not forgetting you'll be needing a chunky PC to use it properly costing far, far more then a PS5 and VR2. Sony should be commended for making this possible in a cheap and streamlined, user friendly fashion.
Also, because every PS5/VR2 combo has the same features, developers will be more likely to effecively using or optimizing their games to use these.
Regarding the teardown; it looks very well engineered and I'm impressed. Also a good sign that the cable can be disconnected without too much fuss, speaking as someone who does console repairs. Cables for it will most likely not be supplied by Sony but I'm betting we'll bee seeing them on AliExpress eventually, maybe even longer ones.
I have no illusion that VR will replace flat gaming but for me it'll most likely be a very nice addition even if the library almost certainly won't be as impressive. Maybe some triple A titles will somehow incorperate a VR mode even if it is playing in VR 3rd person.
I hope to receive my unit this Wednesday so I can experience something truly nextgen! GT7, RE8 and CotM are already in place.
