Nvidia was aiming for Q2-3, so it might be half a year before we will see the new card. From what I know AMD is buying out all avaible silicon to push their HBM2 card before Nvidia. Cards worth buying are usually released at the end of the cicle (gtx x80, x80ti). This might change with the new memory, but I wouldn't hold my breath. Aha, I might have to update myself regarding the time-line! At any rate, I think this is such a big tech-leap that it might be worth waiting for, at least for me personally but then I have a pretty decent system as is.
