It's not about not caring, it's about the internal development cycle at Nintendo. Of course they're going to be focusing on their new portable launching early next year. Look at the DS for example for the past two years, not a whole lot that has come from Nintendo but the system has had a great library to choose from due to third party support which meant that we didn't see these accusations. Had Wii followed the DS model perfectly, we'd have quite a large amount of third party support right now and people wouldn't notice the lack of Nintendo support coming next year.
That's not to say they have nothing on the way with Mario Sports Mix, Zelda: Skyward Sword, Wii Relax, Pikmin 3 and Miyamoto's new IP (he mentioned launching a new IP for Wii next year) all looking to arrive in 2011.
