Man, how many times have I told you since November? You still don't believe me?

Feb the earliest (which now we know will NOT happen), most likely late March, and possibly April.
Right now I am betting on April.
You know how NV embargoes information about sample cards right? Well, I am under no embargoes with NV currently. Chinese New Year just ended so the world over there is just spinning up this week. We might possibly see some sample cards in the first week of March is what I am guessing. But that is still iffy.
I don't see any way possible that NVIDIA is going to have any quantity of 400 series cards on the shelf before September or October.
The build kits have been delivered and some quantity of GPUs have been shipped, but that quantity is very small.
