Given the debacle every time a new Apple product is released and the massive undersupply thereof, I don't think they're too worried about not having enough to meet demand prior to "release". To be fair, I imagine that is out of VF's control given the nature of the fruit empire.
Official launch date was this Wednesday (the 22nd). I would've hoped that they would at least have sent a memo to the stores letting them know that the product is coming, even if it's going to be delayed by a couple of weeks, otherwise the response I got of "*chuckle* maybe in a couple of months" may put them off waiting.
Apparently there was an official "Launch event" in Auckland on the 22nd and the device was supposedly on sale as of yesterday. It does say "selected stores" - maybe its a couple of stores in Auckland only at this stage?
