Graphics Designers/Artists: Your thoughts on iPad Pro vs Wacom CintiqQHD Touch?

Okay everyone...It's that exciting time in every designers calendar wish list.

So, most of you might already be aware with newly announced offerings from Apple.  HOWEVER, one of which stood out for me was the 'iPad Pro' in particular.  For a long time I've been thinking of replacing the Wacom intuos5 with something...Urmmm - Direct? Something Natural? like... Hand to display? i.e: ' All-in-One Computer and graphics tablet' without being attached to the PC (Old generation of Cintiq) whilst being truly mobile.

There is newer product from Wacom that is now 'All-in-one'.  Certainly looks interesting BUT, What about the new iPad Pro for artists with4K Display and powerful enough to Edit3 Streams of4K footage:)   What are your thoughts? Which one would you get and why's? 

Surely, it's fun to have Photoshop/inDesign/Illustrator on the go right? I wonder how3D intense applications with Global illumination Renders will handle be on tablets / Graphics Tablets in the near future?

Obviously speaking from Artistic POV of these devices. But not limited to.
