I would like to say that regarding "Nintendo users don't buy third party games", at least accepted by the media, fallacy Wii shows otherwise. Lots of crappy third party games have had very good sales, games like MadWorld or The Conduit didn't deserve to sell more than 1 copy and yet they managed to do very respectable figures. B tier franchises, I'm being generous here because I should say C tier franchises, only have a chance to sell well on Wii because 99.99 percent of these games would have bombed terribly hard on the HD platforms.
Out of Monster Hunter Tri, which according to Capcom's shipment figures did it really well, and Resident Evil 4: Wii Edition no game deserved big sales. Unfortunately in my opinion these two games are the only real AAA titles Wii has. Yes, I know there are very valuable niche gems, but these games aren't supposed to set the charts on fire.
I can't see in the future a change of paradigm in third party support, they are too stubborn to change their erratic trayectory, they'd rather go out of business before accepting they were wrong with their business strategy.
