Did publishers make mistakes? Did Nintendo make mistakes? Should Dead Space Extraction have bombed? Are THQ nuts when they say there's a missing core audience on the Wii? Was Deadly Creatures any good? Are big HD bombs like Dark Void going to put companies out of business?
These questions are really irrelevant in the grand scheme of things. All the discussion of platform strategy is interesting, but when it comes down to it most people here--especially in threads that are more about software support than about sales--are talking because they want to play games. The only question that matters from a gaming perspective is "Will I get games I want for my Wii?".
Here's a list of announced third party games for the Wii (exclusive or multi with Wii lead, excluding shovelware compilations):

That's the lay of the land right now. That's literally everything that's announced and not released. We have release schedules, commentary, and localization options for most major publishers for the next year or so. E3 will of course bring new announcements, and I'm sure there'll be some great ones, especially underdog niche gems, but the balance of power is locked in at this point.
Eventually there comes a time where it doesn't make sense for every single thread where a publisher basically says they're not putting core games on the Wii to have ten pages of arguing about whether or not the Wii has a core gaming audience. Having the same argument three times a week every week with no new data or insight for more than a year is insanity.
We're certainly past the half-way mark in the generation at this point. The Wii has lead the whole way. Any pattern that is going to emerge has emerged. If you're happy with what you're getting on the Wii, awesome. If you're not, that's awesome too but keep in mind that the situation isn't going to change at this point.
