Do we have to rebuy our Wii VC games if we want to only use the Wii U VC? (Part 2 and Conclusion: Yes, but at a discount)

The end of an investigative series.... Nintendo finally gave the answer today in a Nintendo Direct. I insist you watch it before reading any further.

Here it is, 7 minutes into the video:

I started my investigation into this issue here:

Up until now I never made more than one post on this subject because there has been no extra information released since, leaving us fans in agony for months, worried about losing ownership of the games we bought.

The official answer to this question is "Yes, but at a discount on each game", where "at a discount" is only there to make the "Yes" part not seem so horrible.

In other words "No, but there's an upgrade charge on each game" where there's a higher charge on SNES games for some reason.
Opine of that what you will. I'm going to be asking more questions such as "Do the games play in 60Hz?".
