Well depends what you consider by "that far" listening to Jay, I'm 100% sure he's already got a card, just the way he says stuff like "I'll answer questions as far as the NDA allows", or something along those lines. And if Jay has a card, Linus has a card, and probably Hardware Unboxed as well, etc.
You sign an NDA before you get product, not after. Nvidia shared a ton of information with the press a day or so after the official announcement, stuff in there was likely under NDA. Hardware Unboxed just released a video yesterday where they said they don't have a card yet. Anytime reviewers talk about when they get this stuff, it's never "yeah, we've had it for weeks" it's always stuff like "we had to do all this testing over a weekend" or "we weren't given enough time to run all the tests we wanted" etc.
