No then they will find another reason to hate Nintendo

People can hate on nintendo all they want,but they just keep proving people wrong time and time again. Sure they've had some misteps,but more times then not they get it right. Nintendo is one of the most loved and enduring companies in the world. That's how I feel about Nintendo.

I think developers hate Wii not because they can't make games as good as the first-parties but because when they do it, the games don't sell. On the opposite side, if they make some low cost shovelware it sells very well and they earn a lot of money. See Ubisoft, for example. They know how to make great games. In fact, it was what they have done all those years and its games sold a lot. But on Wii, they have things like My Fitness Coach, Gold's Gym: Cardio Workout and Just Dance. At first, they didn't care about Wii. Now, they see it as a good cow where they can get some milk to the HD projects.

First party has an advantage over third party with it comes to time and resources for developing a game. Most third party do not have the money up front to develop a game for 1-2 years so they rely on a publisher which is interested in making a profit quickly as possible.

I would think it's hard for a third party to sell a game that's push Wii (very dated) gpu to the limt to a publisher unless it was Big N. It's a lot easier to sell to a publisher  a low cost, quicker developing shovelware where they will make a quick profit.
