A while ago @OnLeaks and uSwitch created some very nice looking renders of the LG Nexus 2015 and Huawei Nexus 2015. Now the same leaksters are up to a new trick, creating a detailed 3D render of the iPad Pro, as shown below.
Rumored to be introduced next week, on September 9th, the 12.9 inch iPad has been the subject of renders before, but not as detailed. The video you see here was created with the aid of case manufacturer data, basically measurements of the slate. The 12.9 inch iPad Pro gets 4 speakers and a Force Touch stylus, plus it is rumored to debut with iOS 9.1 preinstalled.
This version of iOS is said to be tweaked with special Siri capabilities, taking advantage of the bigger screen estate. The December 2014 CAD design of the iPad Pro is also compared to the June 2015 CAD model. The basic format is typical for an iPad and involves an unibody metal case, with reasonably narrow bezels and 4:3 aspect.
The tablet is quite slim, has rounded edges and that interesting extra port on the side seems to be gone now.
