No. If there are any new cards from Nvidia in 2017 I would expect the 1080 Ti and maybe a slight 16nm refresh at the end of the year. Unless AMD pulls something out of its hat soon, the GTX 1080 has no competition at all right now. There is no incentive to release anything faster.
Volta is slated for a 2017 release but Volta is for Professional cards. At least right now.
