Images of what appear to be a mockup version of the upcoming larger-screened "iPad Pro" depict either a secondary Lightning port or a USB-C port on one side of the device, suggesting it could potentially have multiple methods of charging and/or the ability to support accessories like keyboards and mice. The pictures, which show the mystery port, a headphone jack/speakers, and the camera, originated on microblogging site Sina Weibo and were shared by Italian site HDBlog.
Case manufacturers and other accessory makers often create dummy models of upcoming Apple devices to get an early start on the development process, and the tablet pictured in the photos is likely one of these mockups. Most of these models are based on rumors and leaked schematics, and while they're frequently accurate, there have been errors in dummy models for past devices.
Given the design similarities between a Lightning port and a USB-C port, it is not entirely clear what function the extra port serves, but a recent rumor from The Wall Street Journal pointed towards the the possible inclusion of USB 3.0 ports on the iPad Pro, potentially allowing the device to connect to a keyboard or mouse.
Aside from the Lightning port, the other images shared on Weibo show a rear camera with light sensor and microphone, and a headphone jack adjacent to a row of speakers. Rumors have suggested the iPad Pro will have speakers and microphones at the top and bottom edges of the device for a stereo audio experience.
Apple may be targeting a September 2015 production timeline for the tablet, so it may come alongside new iPad Air and iPad mini models this fall.
Update: We've received word that these images were originally shared by Dutch site vandaagapple.nl [Google Translate] in February.
