I agree - IIRC, for all the bluster about wanting a 19mm spaced 5er, very few were actually willing to put their money where their mouths were...
To be fair, the offer was only for something like 30 days with no previous warning. Not everybody has a stash of cash to put on a SR5 at short notice like that. It was an offer designed to fail.
In addition there were other bits like only available in one colour, one fingerboard option (I think), taking only direct orders (no dealers)... something else. The guy is not an idiot, and he was more interested in "proving" he was right than in anything else, so he set the conditions to favour him.
