Just went to PJ Digital Mall and went in the one Apple store there. The staff was putting up iPad Air cases and screen protectors, so it's definitely coming real soon.

(Quick tip - if demand and supply was the same as the iPad Mini launch, I would suggest going to "less popular" (but up-to-date) Apple retail stores compared to say, Machines MidValley or something like that, unless you like to queue up. Or just order online.)
