I wish to get gtx 2070 or gtx 2080 too 
But I think it wouldn't be available in 2017, maybe in the first quarter of 2018.

The current NVidia roadmap as I recall is saying "1H 2018" for their 10xx refresh (might be 20xx but I'd bet more likely 11xx series nomenclature).
Usually they will be late from their roadmap, so it will be available at 2nd half 2018, lol~~
