My WAG was < 24 hours because it's INFI and "limited quantities" (although how limited is anyone outside of the shop's guess). However, War Dogs are relatively expensive for a Scrap Yard knife, which may tend to limit order quantities, and I didn't see anything about them on the BladeForums Busse Combat sub-forum when I looked earlier today, so hog participation may be light.
I recall that SS4s sold out very quickly, although I think S5 LEs lingered a bit -- of course, S5 CGs had just taken a big bite from many folks discretionary income and I even remember discussions about whether the LE was worth twice as much as the CG. In this case, I think a fair amount of demand has built-up in the yard, especially among those not saving up for a pilgrimage to Blade -- I'd guess is that there are more available than there were SS4s, and more demand than for S5 LEs. It's a sleek looking knife, and I intend to order a few if I see them hit the shelves.
