There's a surprising lack of buzz surrounding the anticipated introduction of new iPads in October. I suspect one reason is that we already know a fair amount about the fifth-generation iPad: it'll be thinner, lighter, and narrower, with narrower bezels left and right, and a form factor similar to the iPad mini. Another reason may be that no one is expecting anything major, unlike last year when the iPad mini was announced. So far it's a bit of a mystery what sort of upgrade the mini will receive, with some rumors saying it'll get a retina display and others saying that a retina model won't be ready until next year.
One bit of news this week is that the iPad will have the same colors as the new iPhone: silver and space grey. According to MacRumors, one rumor circulating is that there will also be a gold model, but so far no photos of gold casings have appeared. You can see recently posted photos of the silver and space grey casings of the new iPads on SonnyDickson.com.
The most interesting rumor of late comes via MacRumors, which is reporting that Apple is working on a 12- or 13-inch iPad. This rumor comes from a Chinese website that even names the company that will be a supplier for the new device. Of course, Apple is always working on various prototypes, even doing test manufacturing runs, of new devices that they never bring to market. (They do this to see which size they think people will like best and whether it can be manufactured efficiently and cost-effectively.) So there's no way of knowing whether we'll see a larger iPad. But it would certainly make a splash, and I do think there'll be a market for it. One rumor suggested that it could launch early next year.
