To the first part : That's Sony's responsibility to prove, and I fully expect them to be the one to justify it. They've made the case that the core unit will be fully vr capable, but this upgrade is apparently just that, an upgrade, so it remains up to them to justify its purpose and existence across the board. I'm not trying to defend Sony, just to say that we've got market trends showing consumers have embraced various similar products.
To the second... I can see how it could come across that way. Not my intention, but I'm also on my phone, so my bad, I'll own it. Regardless, my point want to dismiss people, but to try and point out that it's foolish to be extremely dramatic about something without any confirmation from Sony themselves and only be operating on assumption of the worst or best case.
