x299 what's going on???

I maybe living under a rock haha but is there a reason computer stores don’t stock alot of the x299 boards?? Some stores only have 3 or 4 to choose from but they have over 50 of the 1151 boards to choose from? Are the x299 no longer? I just checked one major store and they are out of stock on all x299 boards like what's going on am I missing something????

Cheers
