I ordered my FTW on the 30th so I assumed that I was way down the queue. Decided to check with OCUK and they told me I was 48th in the queue. Looking at your post, I think that they may have been wrong!
Suppose some could have cancelled orders...
Almost certainly. Buyer's remorse is going to be high with something like this. I know, I had to rush to cancel an EVGA FE order on another website last week.
Nvidia's incompetence on this occasion has probably given a lot of people enough time to think and change their minds.
