You do realize that those screens have special sensors right? You cant use a wacom pen on just any touch screen. The screen must have a special digitizer which is like a second plastic glass below the screen. This wont work. Never. Because its not a software issue, its a hardware one.
Going back to the topic:
-Bluetooth headphones and mic compatiblity
-Audio jack on pro controller and joycons.
As it is right now, you need 2 pair of headphones (one for the console, one for your cellphone) to use voice chat, and 4 ears to wear the 4 headphones!
And you cant be at the bed using the docked console on the tv if you plan to wear headphones unless you have a 3 meters long audio cable.
Frankly the thought of that gives me headaches already. Its really non comfortable. The procontroller should have an audio jack at least.
-fix left joycon issue
-more battery
The revision will likely come with bluetooth compatibility, a pascal chip for 5 hours battery and the left joycon. Kinda regretting supporting the console from day one now.
