Seriously though, I still need to see good arguments about why this is good for gamers/consumers in general and better than the current 5-6 years cycle (also for PC gamers considering the current console generation models I rings a lot of benefits to PC gamers too indirectly).
Nah, your wrong. Phones change every couple of years or more as they are subsidised contracts (and fashion accessories - people like showing latest tech in the pub).
This does not apply to consoles, a box hidden under your TV. People change cars or TV's to show off/ have nice things, but tech specs of a black box. Not so much.
The reason we have to have iterative consoles in 2016/2017 is because 28 nm >> 14 nm.
Its a massive process improvement and power triple almost for the same price. Think about that, then lets discuss. Its not happening now because its cool lol. PC gamers are also upgrading en masse, big performance for low power and this is the year.
When will Ps5 / Xb2 launch - well, when we go from 5 to 15 TF for same price it would be a given. Will that happen in 1 year ? hell no.
Neo and Scorpio will be good until > 10 TF is cheaply attainable to the masses. 10 nm roadmap and HBM2 maybe, but it might be more than 3 or 4 years.
Nobody is going to ditch a 5 TF console for a 7 TF console that is indistinguishable in how games run because Sony / MS or Nintendo think there is money to be had.
Think about it this way, new tech is needed when we need to move to new levels of play. We are 1080p30 now for allot of games, enthusiasts are hungry for 1080p60 for games like witcher 3.
Once you have Witcher 3 at 1080p60 and souls games etc and GTA5, what is the next enticing thing ? VR maybe, but a new console in 2020 that plays 4K = who cares ? It will take 4K60 before people move en masse.
