Crime? Really? A discount would be welcome but it could only work for digital.
It can really only work digitally, yes. But discount pricing for those that own MK8+DLC Pack 1 & 2 digitally should be offered. Those digital owners should get the game for $30 at the absolute max, $45 for those that have the DLC packs would be a nice gesture as well.
That would be more than fair considering it is essentially the same game with a higher resolution and a 3rd DLC pack added in. That on top of the fact that that customer was basically a Beta Tester for the Switch experience by buying into the Wii U.
That is unless Nintendo just plans to go into total DGAF mode and going forward expects ports of previous games with a bit of added content merit full price regardless of previous ownership. This will sadly probably be the case.
That said, this is an insanely good value for people new to MK8, best value of the year in gaming behind BOTW, imo.
