Right now it doesn't matter much to me since I own all the Wii games announced. Frankly, there are very few games that I don't own on Wii that I'm still looking for. The biggest would be Fire Emblem: Radiant Dawn. Other than that, it's some Mario Sports titles, Sonic titles, and Harvest Moon titles.
However, I have really wanted to replay the Metroid Prime games and getting all 3 for $10 is a really, really, great deal.
