Thanks for the post, I'm on the fence too (On 4.1.0 atm) and since I got the TX preordered and pirating single player exclusives is all I care about on the switch as far as hacking the console goes, so I'm thinking on updating too so I can enjoy things like playing paladins on the go and finally get back to playing ARMS online. For emulators, every android device I have is more competent at it than Nintendo's console, specially since I have the 8bitdo controller. Freeshop would be damn nice but it's not happening it seems.
Just a few observations
1 - You can't really play Wii U on the go. I can't even move my Wii U pad to another room in my house without losing signal.
2 - You could just sell your Street Fighter copy factory sealed without taking much of a loss.
Thanks!
