How do I express my displeasure toward third parties?

[Kenny]

I recently bought Call of Duty: World at War for the Wii, and I'm finding it to be a worthwhile offering so far.  Even after hearing about the stripped down multiplayer and the removal of the Nazi Zombies, I felt it important to support quality third party games on the Wii.  However, I realized that I've hit a bit of a conundrum when it comes to the message I want to send.  See, what I want to tell third parties is to stop watering down the Wii version of multiplatform games, which is pretty much standard if there's even a Wii version to begin with, and to start giving it at least as much in the way of development resources as the PS360 versions.  However, I (and the Wii owner base at large) only have two options available: Either buy the game, or don't.  Here's the problem:

If watered down games do sell (i.e. I buy the game, hoping to entice them to start dedicating more resources to Wii development), third parties will interpret it as being good enough to half ass the games they put out for the Wii, and never improve the quality of their work.
If watered down games don't sell (i.e. I don't buy the game, hoping to tell them that I won't support low quality games), third parties will interpret it as the lack of a viable market for them on the Wii, and cut back on development.

I'm sure everyone around here has seen this all-encompassing no-win scenario against the Wii in debates over third party support.  No matter what I do, I can and probably will be misinterpreted in the ways I described.  So the question is this: In voting with my wallet, is there actually a way to make sure the devs get my message of wanting them to start taking the Wii seriously?
