I think fall 2019 is more realistic.

Anyway it would make sense for them to release a very high-end PS5 focused on VR and even bearing some losses to do so.
If they succeed to make VR gaming viable to the mass market they would gain a great competitive advantage for the coming years.

No chance to see PS5 releasing this year.

Sony releasing the PS5 this year would kill off their main cash cow, it would be hugely stupid. Sony has done stupid in the past but there is zero chance of this happening. 2019, maybe, although I expect a Q1 2020 release.

yes.  imo, it would also be a burden on consumer wallets. If this were true, I'd be very interested to see pricepoint and effect on sales, i think kinect hurt Xbox one pretty badly.

As for rumor, 2018 seems unlikely, but so does 2020 that some are saying.  PS4 is doing great, but Nintendo now has a hit console at opposing time to Sony.  Waiting too long could leave N with all the momentum.  it's an exciting time since frankly power doesn't matter anymore.

Its more like a co-proccessor, a small extra chip, so no.

You see that little box, where all the wires go, between the PS4 and the PSVR?

That would probably not be needed in the future for PS5, as a result, of whatever is in there, being inside the PS5 instead on-chip.

Less wires, easier setups, lower costs of PSVR.
(however I suspect there will be a PSVR 2.0)

I could imagine one developer utilizing the dev kit right now and that's Guerilla Game. I can insane and Third party as well especially Platinum Games now that Nier: Automata is out of the way over a year. Naughty might honestly be developing for both PS4 and 5.

If PS5 releases first then XboxNext might be a little more powerful. Are there any rumors on Microsoft side?

O yeah, so its more like an additional "onboard controller" then a reserved CPU-GPU pipeline - thanks;)

2019 seems too early, but much more plausible. I don't really see the point of pushing the ceiling on graphical capabilities when so few are able to with what we have now.

Thank you!!!

I don't know why people can't use a little bit of logic
