Hmm. There's a limit to how long you can keep doing the repackaging thing.
With Apple muscling the DS with iPod Touch and iPad, and with MS muscling the Wii with XBox360/Kinect, Nintendo needs more than a new box and pigment in the plastic.
I bought the XBox/Kinect bundle and a couple of extra games. It's cool technology, and Dance Central at least is a great title, but the regular XBox interface is still a mess and the system is far too convoluted compared to the foolproof approach of Apple's iOS or even Nintendo's current system.
I'm spending 40% of my time with the Wii, 50% with the iPad, and 10% with the XBox. Aside from getting new games, I have no incentive to spend any money on Wii stuff, and I may just spend more on the XBox as time goes by. I'm sure I'll get used to its logic.
So Nintendo needs to compete on at least two fronts to keep someone like me: better video--hey, Nintendo, we all have high definition gear now-- and innovation in control. As nice as the Wiimote+ is/was, it's not Kinect competitive, so I hope they've got something in the bag.
FWIW, I don't think Sony's in any better position, probably worse.
What I can afford, when I can afford it...
