I disagree. If Nvidia or AMD or Intel, whoever, claims to launch on review day, and there is ample stock, that is a hard launch. If they review and state the launch date later, that is still a hard launch for the stated date. If in either case stock isn't there and purchasing is difficult to non-existent, then that is a paper launch. This is all I will ever agree with. makes the most sense. Logical.
I think people are just being a little pissy because AMD got a bunch of crap about the Nano launch being a paper launch, when it was essentially the same thing. The card was talked about at the Fiji launch with expected availability in summer, then in late August they gave the launch a date (Sept 10), and then on the 10th they launched in quantity.
IMO, a paper launch is more like Broadwell-C. Intel launched it, but it was impossible to find anywhere for many months after. It's launched on paper, but impossible to find. The 1080 isn't a paper launch, since it hasn't launched yet.
