I was as excited as you. Until my 8bitdo device arrived, and I found out the vibration does not work with he wii u pro controller..... I have not find a fix... if you do keep me posted...
Before i didn't care about the vibration, but since the "HD rumble" of the joy cons is really good in my humble opinion, well, it's disappointing that there is no vibraton with the wii u pro controller
