I just bought a second copy of TP HD, so I could get the Wolf Link Amiibo. I bought the digital version first....I didn't care about the Amiibo, but I saw how you can use Wolf Link on BoTW and I said screw it and bought it. I guess the good outcome of this is 1) If Switch transfers all downloaded Wii U content to the Switch, and it disallows you to use the digital stuff on the Wii U afterwards (Like the Wii U transferred all digital Wii content and saves) I can still play my TP HD on my Wii U in the future. Worst case scenario is I own it twice, or 4 times with my older GC and Wii Copies. Sigh. I guess since WW HD is at Walmart for 19 dollars, I should just pick that up too.
