Some rumors are suspect, because the source may or may not know what he's talking about. But when it's the head of Foxconn who makes the assertion, you have to figure he knows what he's talking about (since Foxconn is the major manufacturer of Apple's iOS devices). And earlier today China Daily, and English-language newspaper in China, reported on a speech by Foxconn Chairman Terry Gou in which he said that Foxconn was "making preparations" for Apple's rumored TV set, though development and manufacturing haven't yet begun. He also said that a recent partnership between Foxconn and Sharp was in preparation for an Apple TV. There has been speculation that the two companies would produce Indium Gallium Zinc Oxide (IGZO) panels for the new TV set.
[update: AppleInsider says Foxconn denies making a statement about a forthcoming Apple TV set.]
You'll be hearing more about IGZO. As I understand it, these panels allow high resolution but use less energy. I read recently that the current iPad, with its thicker and heavier design, was a kludge. Apple wanted to up the resolution, but it also wanted to do it using IGZO. But IGZO wasn't quite ready. The manufacturers simply weren't capable of producing the quantity of defect-free panels that were needed. So Apple went with current technology — which was a bit of a compromise.
And another hot rumor hitting the blogs comes via iMore, which says that Apple is targeting an October release for its 7-inch iPad, and that it will be priced between $200-250 for 8GB. When they say 7-inches, though, they aren't stipulating the exact size and say that it could be the 7.85-inch size that has often been rumored. iMore says that their sources say that it'll be just like the current iPad, but scaled down to the 7-inch range.
