I would expect the consumer volta (aka Ampere) to be $1500. Call it 2080 Ti or Titan XR or whatever. Than the rest fall into place. I think the next series is getting a $50-250 price hike.
Maybe Titan A at $1500 and a 2080Ti releasing 8 months later at $999 ? And a 2080 at $799 since the x80 isn't usually a whole lot faster than the previous gen x80 Ti card.
