Wouldn't be the first time:
>"But take a look around and you will notice that this sequel, which may advance the series more than any other, has been more or less ignored by Nintendo, as the company chooses instead to spotlight in-house creations like Brawl and “expanded audience” efforts like Wii Fit, both of which are scheduled for release well after Corruption. Were Retro's latest set for release next year or even this December, like Brawl, we might be able to understand the disappointing lack of exposure for the game, but Prime 3 ships fewer than three weeks from now."

>"The point we're making is that by no estimation is Corruption a throwaway sequel. Clearly, a lot of development time and resources have gone into the creation of this sequel, the third and final act in the Prime trilogy. But here we are, three weeks away, and we remain excited for the product practically in spite of Nintendo's lackluster efforts."

>"E3 2007, Nintendo showed only a few additional seconds of Prime 3 at its pre-show Media Briefing. It instead chose to dedicate the event to the casual audience, which is understandable. Later, though, as the company showed off games like Galaxy from the official E3 floor, it kept Prime 3 locked away in its private suite and even then allowed press very limited time. When all reactions have proven to be positive, it's a mystery why the company hasn't done more to build and maintain excitement for a project that has the potential to be one of 2007's biggest."

>"What is most unnerving about the lack of awareness and hype for Prime 3 is that as we head into the final stretch, we still don't have any idea what Nintendo's plans are for the game, if any. We've heard no mention of developer blogs or studio tours, no hints of a major advertising campaign, and we're still not even sure when we'll get the game for review"
