I agree with the founders edition comment wholeheartedly. Nvidia have never done it before and I hope never do it again.
I was getting at the fact that Nvidia wanted to beat AMD at launching cards on a brand new node as a bit of marketing one upmanship. It all sells cards and getting a paper launch in before the opposition, when you are expected to be 6 months behind was a big plus point......the only thing is....they weren't really ready to supply those cards in abundance, but the launch gave the impression that they were. So a race to the new node, not necessarily for direct competition between cards in the same tier.
We have all known for many months which way AMD were going to be producing their cards in this Generation, so no surprise that there is no direct competition for the 1070/1080 yet....So don't see what you are getting at either.
AMD said that their mid/low end would be out in summer and their higher end would be Q1 2017 and so far they have been spot on......other dates have been pure rumour and speculation by people outside of AMD/RTG.
