It should be interesting ...
Between games like Metroid Prime, Battalion Wars II, Medal of Honor: Heroes 2, and Resident Evil 4: Wii Edition it is clear that the point and click interface of the Wii is far better suited to 'shooter' games than any console controler that has ever been produced.
The problems Nintendo will have attracting 'shooter' developers is many of the good FPS developers are graphics whores and the Wii doesn't have the processing power to appeal to them, and many 'shooter' games have a focus on online gameplay which (currently) the Wii is not that well suited to. I don't really think the processing power difference will keep developers away for very long being that developers will head towards large userbases, but Nintendo should possibly think of changing friend codes to making them unnecessary in 'Mature' games and including voice communication some how.
