I will, but I don't plan on buying Wii U immediately anyway.
In the past I sold my Megadrive to fund the N64 purchase, I had a mid-term swap of N64s (sold my original but bought my sisters from her a week later) but didn't sell the second N64 to get the GameCube. To help fund the Wii purchase I sold the GC before the Wii launch, and then finally sold the N64 about 2 years later.
With the Wii ability to play GC games I didn't have to sell them, so I only miss the ones I sell intentionally (REmake being the only one I wish I had back)
I did of course sell my MD and N64 games with their respective consoles... I miss Micro Machines from the MD, and the usual classics from the N64 (Perfect Dark, Blast Corps, Pilotwings, Star Wars Ep1 Pod racer... I don't miss Goldeneye so much as I recognise it has aged, and I feel I maxed it out back then, whereas I didn't get to spend as much time with Perfect Dark)
As such, if and when I get a Wii U... I don't think I will be selling the Wii as I don't think I could give up Wave Race, Rogue Squadron, Eternal Darkness and Timesplitters 2. And even if I never planned to play it again I don't think I would sell Windwaker until an alternate method of playing it arose.
