A render of the supposed 12.9″ iPad Pro has been leaked on Twitter, by @Onleaks. It shows a tablet measuring 223 x 306 x 7.2mm (this area has a 14.9″ diagonal, which could feasibly be a 12.9″ display with bezels – TA), with a USB-C port. The tablet, along with a 15″ Macbook, is expected to be launched at WWDC 2015 (starting on 12th June).
