So, now that Apple has released an iPad Air, how far behind is the iPad Pro?

Here is my wish list for the iPad Pro.

Intel x86-64 CPU, quad core

 

8-16GB RAM

 

512GB storage

 

14″ display with a 4:3 aspect ratio

 

QHD resolution

 

Digital pen

 

OSX running iOS in windowed mode

 

USB 3 port(s) with the ability to charge from an external keyboard/battery

 

12 hour battery

 

8Mpxl camera, for scanning and OCR

I’m probably way off, but that is what I think I want in the next generation and form factor iPad.
How likely do you think that I may be close?
What would you like to see?
