I think you're confusing VC with BC.
VC currently goes up through N64 and the rumor was adding GC to that list of support, which is certainly possible if they've built an emulator that would work on Switch.
Putting Wii or WiiU games would be more like what they did on WiiU with Wii games. These are cases where they just ported the past game to the new console. Mostly commonly as a digital title. I bought Metroid Prime Trilogy that way and its awesome.
I think what this does is solidify the notion that even digital games are not going to be BC on NS. Where previously there was a possibility as they only stated physical BC. To me, this quote is more encompassing of a total no BC approach for any past system content.
Considering they also haven't talked about VC yet, I'm giving up on my hope that VC titles would just move over this time and instead think if/when VC is announced we'll see new features and thus a cost associated. Hopefully, this will be similar to WiiU and a low cost with decent new features (online play?). I do hope that it doesn't rollout slowly again. You'd think the core emulation and functionality could just be extended easily with whatever new feature they were adding. Also hope they don't keep losing fidelity from the original game.
