$10 Metroid Prime Trilogy, anybody buying who own the separate GCN and Wii games? Differences?

I have all three games in their original format, and I used to own the trilogy on the Wii disc, but hurried and sold it as soon as the Wii U download was announced. I'd like to sell my discs of the standalone games too, but I doubt I'll have much luck with that.
