More iPad Pro Rumors

Now that the iPhone 6, the Apple Watch and the Retina 5K iMac are old news, some more rumors on the iPad Pro are trickling in (via MacTrast). But other than the size of the iPad Pro, 12" and that it might feature some "Pro" hardware specs, like stereo speakers, for example, nothing new here... But my big question is as to how the software differentiation of this iPad "Pro" is going to be implemented (like I mentioned last year)? 

If we see an iPad Pro released next year, I would predict that we will also see a much more powerful evolution/version of iOS emerge in conjunction with the mighty rumored iPad Pro.
