Thats not innovation. That is just upgrading what they have. 

I reckon they'll inovate. If I knew what they would do I would be rich by now, instead of posting on a forum :P

My guess is the DS advanced will still have 2 screens, and that one of them will be a touch screen still. It will also have tilt and motion sensing technology as well as the microphone. Hopefully they'll also throw in something surprising as well.

Wii 2 will be more powerful, include a harddrive and 1080p graphics. The controller will be similar, but improved. (more accurate motion sensitivity, and im guessing all the face buttons would be replaced with a touch screen, allowing the 'buttons' to be placed wherever the user wants them to go. Think the prototype revolution controller)

 Sure They could always upgrade, and add new innovation to it, I just can't think of new things right now.

I predict...Virtual Boy revamped.

who knows what theyll do for ds other than two touchscreens and prolly a remodeling of the button layout.

for wii, i hope tehy make 1:1 motion sensing and a decent controller. for me, the controller is a great idea but failed on execution.

 Damn you, That's what I was gonna say.

 That's what they say.

 Then the competition 'fixes' what you thought was working fine all along, and suddenly they're the market leader.

The next hardware from Nintendo might not be as revolutionary as this generation, but resting on their laurels would be a good way to give the competition a chance to strike back.

the answer to "upgrade or innovate?" really depends on a few questions.

- will the expanded audience be bored if the control scheme is only a sleight improvement or is another innovation required?

- will the competing hardware manufacturers implement an innovative control scheme?

- will another innovation need to be implemented to counter any possible actions of the competition?

Nintendo didnt really ask those last two questions when developing the Wii because the concepts of PS3 and 360 were predictable. they'll probably ask them this time round but will ask the first question alot more as it is a much more sensible approach.

now another question that may be asked is: "can an upgrade in data processing efficiency result in any significant improvement in the Wii remote control scheme?"

that will probably be asked to determine how much improvement in graphical/data processing power Nintendo will go for.

well i think we'll be looking at something that is roughly in the range of PS3/360 maybe a little more. by the time of next generation, HD adoption will be a much higher percentage. Nintendo will most likely reflect that with their system power.

the reason i dont think it will be too much more powerful than PS3/360 is because Nintendo will be looking at that US$200/300 price range again. Nintendo have realised that the expanded audience is where the majority of sales are and the price will refect that. manufacturing anything more raise the price too high as Nintendo will still be looking to make a profit from hardware.

so that will create the questions: "how much of that US$200/300 is left after the power upgrade and profit?" and "is that enough for any extreme innovation?"

personally i dont believe Nintendo will introduce another radical control scheme. but that doesnt mean there couldnt be any significant improvement in the Wii control scheme. i'm hoping that they combine a camera with the sensor bar to allow better reads of motion, pointer screen position and depth perception. i'd also like the nunchuk to have the pointer functionality.

For Wii I reckon they'll upgrade graphics/processing tehcnology to level of the 360, prehaps add more ssytem memory and either use a Hard drive or some form of flash memory for storage. Upgrade controller as well to be more accurate, usubale etc but no major innovations I don't think.

wii 2 and ds 2 will offer you BC just like ds and wii so there will be probably small changes in those consoles(maybe ds 2 will offer only touch screen without buttons).
