No, they probably wouldn't have said anything. They don't break out sales within product categories, ever. They don't break out sales by iPhone model (4s, 5c, 5s) and never have, and since the mini launched they have never broken out sales separately. Announcing that "we sold X million" iPad Air on launch weekend would give analysts and competitors a bit more information about Apple's sales mix than they apparently want to give.
It isn't unique to Apple. Samsung breaks out even less information than Apple, and doesn't announce total unit sales except some occasional cherry picked data.
