According to Industry expert Rhoda Alexander, director of tablet research at IHS, the stock for the new Retina display iPad Mini (2nd-gen) will likely be "ridiculously tight." According to several analysts including Rhoda Alexander, estimates on the amount of new mini iPads that Apple can produce this time around is only about a third of what shipped at this time last year. This is primarily because of supply constraints for the new product.
The new iPad Air will be available on November 1st, but for now Apple is coy about an exact launch date for the iPad Mini 2nd generation. They only proffered a vague "sometime in November." It looks like fans of the iPad Mini who want to pick up the Retina version might have to stand in those long Apple lines this Fall or risk having to wait a while to get one.
