The only issue I have with this article is that the OP is taking the current crop of Wii games and acting as if that's all there is ever going to be. History repeats itself and this has already happened on the DS. It's teh first 2 years and developers are still in the novelty stage of understanding the controls. Every game we've seen, to date, has essentially been the "Hello World" of motion controls, dressed up so they can keep enough funding to develop a full fleshed game.
Now DS is getting a lot of awesome games, some people doing everything they can with the stylus controls, some doing nothing at all, but all have slowly learned to what extent the new controls will benefit a game and where they won't benefit the game at all. I'm currently playing Legend of Kage 2 which has actually been pretty fun, but all it uses the stylus for is to configure your powerups. Configuring those powerups with classic controls would be a serious pain, but trying to play the game with the stylus would be even worse, so the balance they found really made the most out of the DS.
Same thing is happening adn will keep on happening for the Wii. A huge load of majorly anticipated games are slated for next year. To keep the dry periods from getting too irritating, Nintendo is doing "Play on Wii" titles, which every troll will complain about, but is still exactly what every Wii gamer has been asking from the very beginning; Same great games we've had on Gamecube but demonstrating just how much better the Wii controls alone can make the game.
Nintendo also announced Wii Motion+ and you can bet developers will be jumping on that, complain all you want about how it should have been there from the beginning. Even without it, developers are still testing the waters to see what can be done with the motion controls besides just waggle.
Developers are also learning to push graphics on the console, but instead of it all being "Look you can see the pores of that man's skin and the dirt smudge right over his still bleeding scar that's soaking into each follicle of hair on his eyebrow" we're getting more style and artistic experimentation like what we've seen in No More Heroes and previews of Madworld.
I agree that 360 just isn't bringing any new concepts to the table, and the hardware issues just tanked any favorable opinion I had started to form about their early launch. PS3 is far preferable in my eyes but I agree that they are essentially living on borrowed time with how early they make announcements for things. It gets to the point that even if what they announced would have been a success, people have grown jaded by how long they've been kept waiting.
I say it's 2010 before developers really manage to start capitalizing on what Wii is really capable of. Hopefully by that point, PS3 will have managed to scrape it's way up ahead of 360 so that we can see more developers capitalizing on the advancements Sony has been trying to bring in as well.
