Opposite here, my wii u is boxed up after i got it on launch day and is on stock firmware from day 1, and i use my wii with 4 wavebirds for GC/wii duties.
Nice! That's a good setup! I mainly bust the old Wii out when I go to friends houses to play some Melee, using Nintendont now haha. It's mainly cause I don't have to unplug the Wii U and cause two of my friends use the GC controllers, I use the WUPro and the other uses the DS3.
