Do we have to rebuy our Wii VC games if we want to only use the Wii U VC? (Part 1: The New Wii U VC)

The beginning of an investigative series! Everyone's asking this and noone but Nintendo has clear answers and they're not giving them Nintendo-Directly.

There will be a Wii U VC and it will be completely different to the Wii VC. The Wii VC will still be accessible on the Wii U through the Wii application. So based on my understanding it will be like this:

Here is the inside of a Wii U. On the left is where our Wii VC games will transfer to. On the right is where the new Wii U VC will be, completely separate from the one on the left. The one on the left will not be playable on the Wii U game pad but the one on the right will be.

Do we have to rebuy our Wii VC games if we want to only use the Wii U VC? We don't know yet! We just know that the two Virtual Console systems are completely different.
