Just days ahead of an expected September 6 announcement of new models, Amazon has conveniently "sold out" of its stock of the current Kindle Fire and Kindle Touch, also reporting short supply on other Kindle models. The company, which refuses to release sales or shipment numbers, also claims that the Fire has captured 22 percent of the US tablet market, though it has no significant presence in e-reader sales outside the US, with IDC estimating perhaps a five percent share worldwide.
