PES will be an example used all this year and beyond I have a feeling. It could be the very catalyst to everything that's being talked about in this thread. If PES Wii sales spike, it could very well become the lead version. PES players would actually seek out the Wii as their preferred platform to play the game on.
It's possible, and in many more genres than football. But IF it happens, it will take baby steps, and might not even see fruition this generation.
As I said, Nintendo forced a change on the industry that the industry wasn't ready to adopt. If Nintendo can continue to remain relevant, especially if they can continue to be the sales leader, companies are going to start figuring out how to makes serious money off of its 20M, 24M, 30M, 35M, etc userbase.
But for this to happen, I have a feeling Nintendo will have to lead the charge themselves and KEEP themselves relevant and the sales leader... because it certainly isn't going to happen based even in large part on current third party support. It's definitely possible for them to do this.. just far from guaranteed. Although all they really need is another Nintendogs, Wii Sports, Animal Crossing, etc. Actually, thinking about it, Wii Fit is pretty much make or break for Nintendo. If Wii Fit fails, I have a feeling that eventually Nintendo will take a sound 2nd place to "HD gaming" in the mass market this gen. If Wii Fit succeeds, Nintendo could very well quell "HD gaming" in the eyes of the mass market for the remainder of the generation.
