Here is an article by 3dcenter in german. Using a translator of course and inferring from it, you get a good idea of what's being said. Makes comparisons to previous refreshes with fermi and kepler and how maxwell was an exception to that rule, and of course a pascal refresh. The name for it is rumored to be Geforce 2000 Series, or Geforce "20" Series, rather than Geforce 1100 series. Interestingly, a 2080 Ti is noted here, so its possible that the 1080 ti is on the way, but possibly coming in the pascal refresh. Also makes mention that volta could still be launched on the 10nm mode in 2018.
Longer time was primarily about speculates that by nVidia Pascal in the 14 / 16nm manufacturing directly the generation Volta should begin generation in 10nm manufacturing. This is also not at all wrong, nVidias various roadmaps give exactly this direction. But something was forgotten here, which nVidia also usually not mentioned on its roadmaps: Normally used in nVidia in the younger to middle past a graphics chip series always for two graphics card series. This has already been perfectly lead by example in the chip generations "Fermi" with the resulting graphics cards series GeForce 400 & 500 and below in " Kepler " with the resulting graphics cards series GeForce 600 & 700. But the chip generation " Maxwell " (GeForce 900 series) was an exception here - but which can justify even from himself, the nVidia had driven with this the 28nm manufacturing to extremes and therefore simply was not a great place more for a second, of course, more powerful graphics card series.
