The Japanese blog Mac Otakara, which often leaks iPhone-related info based on supply chain sources, now claims that both those Catcher schematics, and the leaked dual-camera chassis of an alleged iPhone 7 Pro that you see below, are the real deal, and this is largely how the iPhone 7 will take shape as well. The source says that these three dots at the bottom are part of the Smart Connector setup that will make a cameo on the new iPhones, just like it did on the iPad Pro line.
Surprisingly enough, Mac Otakara shoots down the rumor that the iPhone 7 line will be much thinner than the current crop, or that it will have stereo speakers after eschewing the standard audio jack. It does confirm the dual-camera setup on the back, though, so we can't wait to see the real thing, and what Apple might have done with two camera modules.
