First Conduit, then Cursed Mountain, now this!
I think it's very interesting to look at the Publishers of the games you listed...
High Voltage Software, Deep Silver, Codemasters... these are mid-level companies making their moves on the Wii, an area where I think Nintendo should really focus on if they want to garner support. The big companies are too slow to shift strategies (well, Capcom is surprisingly nimble) and too inertially invested in the other consoles.
Nintendo should put effort into aggressively courting companies like Atlus, Eidos/SCi, NIS, Disney, Hudson, and other companies of similar size or market position. These companies are perfectly situated to, I believe, be sold on the concept of becoming the next big thing on the Wii without much competition from Squaresoft, Konami, etc.
