It does make third parties money, but so does PS360 developement. Which makes more depends on a variety of factors and pretty much comes down to the strengths of the developers, the size of the publisher and nature of the project.
I don't think Wii makes developers as much money as some Wii fans I've read tend to think, just cause a game sells 500k is hardly the whole story, and developement costs can easily cost less then marketing.
So er, all console platforms are profitable and a successful third party will have a strong multiplatform initiative.
One thing I do find interesting is that the most successful Wii games have a strong household brand name attatched to them - Sonic, Resident Evil, Star Wars all the way down to High School Musical and Naruto. I think that's a strong evident for how third parties need to approach Wii developement.
