First off, DigiTimes has a terrible track record. Secondly, I challenge you to historically identify an Apple hardware release in the past eight years that hasn't had this exact same story claiming production shortages will constrain initial sales. Thirdly, it never matters. Apple's customers always wait however long it takes to get their next high quality product, even sight unseen, because we trust them to deliver products that look great, are manufactured to incredible tolerances with quality that puts most of the industry to shame, and will work as advertised.
I can hardly wait to preorder in two weeks. This is going to be fun,
