I'll take a heavier and larger form factor every time, if it still gives glare and have a more fiddly sweet spot, then they still aren't good enough imho, it really threw me out of the experience. As a predominantly PC centric player, I was astounded at how much of a superior headset the PSVR was to the Vive, I expected the opposite considering the price gap it had (mind you, Sony have far more hardware experience, so shouldn't have surprised me).
Of course the PSVR tracking was woeful and the controllers dated, so there was that I guess. But as heavy as the PSVR headset was, it was far more comfortable and despite it's lower resolution, everything was clearer, the sweetspot easier to find and the immersion greater, not having glare was the icing on the cake, that totally destroyed any immersion on the Vive for me.
I really hope you're right about the Fresnel lenses, they better be radically better than they were, I doubt it though, plastic crap aint gonna cut it compared to glass.
