I think Zelda will sell in line with previous games in the series, somewhere in the 5-6 million range. It won't sell as well as TP because of not benefitting from being a launch game and releasing during the holidays, but it will still do well. Doing better the Majoras Mask and Wind Waker, but less than TP and Oot, putting it squarely in the middle of the 3D Zeldas. The sales may seem smaller just because prior to this gen Zelda was one of Nintendo's best selling console franchises but now it is not even close to the top.
Kirby I think will also do in line with other entries in the franchise. I'm guessing 2.5 million total. 1m in Japan and America and 500k in Europe.
DKC and Epic Mickey are certainly more wildcards than the other 2. I think DKC based on its release date in America is going to be big, just not near New Super Mario Wii big. I think 3 million in America and and around a million each in Europe and Japan, although I think there is also a chance the game does poorly in Japan. So around 5-6 million total.
For Epic Mickey if Disney advertises it heavily like I think it does and it releases in Novermber or earlier to get the benefit of more holiday sales I think 3-5 million. If the game doesn't get massive advertising than 1-1.5 million eventually. But I think Disney will get behind the title and it will be a hit.
For fun, I think Metroid: Other M will get to 1.75 million, a little higher than Corruption just because the game is a little more streamlined and I think there will be a few people curious about the change in the franchise.
I also think Goldeneye will be a "core" Wii game interesting to watch. I think the game could be big (2-4 million) with heavy advertising. It just has all the features I've been waiting to see for a Wii shooter, brand recognition, online and local multi-player. I think if the game turns out to be at least solid and given lots of promotion it could do well. I also could see the game not get much advertising at all and not even reaching a million and becoming another piece of evidence that "Wii doesn't sell core games".
