Found it, it was by Iwata

From the article

"We are always preparing for the next hardware,"

In terms of future specs, Iwata commented that every new piece of hardware "needs some revolutionary features."

That's a good read! Glad to see they kept in mind that innovation is the key.

 what you say is true but i still dont think it would have as far reaching effects as the Wii mote has. But as ive said before these are just my opinions u could very well be right :)

Maybe.

I'm not sure it will sell as well because the novelty of it won't be a factor. I think many of the people buying it now are drawn in by it. I think a good number of these patrons will say "I don't need a Wii 2".

I think what people are forgetting is that by the time Wii 2 comes out, Wii's controls won't be a novelty, they will be the new standard.

Sure, the grandparents who got Wii just for Wii bowling aren't going to have much reason to make the shift, but well, lets be honest, they might not even be ALIVE at that point in time.

Now, take the kids who grew up on Wii. They WILL be following and anticipating when the next console comes out, and they'll be used to the motion controls, so they'll also be looking for their next console to have similar controls.

The only possible reason that Wii 2 won't do as well or better than Wii is because Wii is simply THAT BIG. It still stands to dominate the competitors just as badly as Wii is doing now.

I think that we will see innovation in head tracking. But you know they always have a trick up their sleeve's. Also by then Nintendo will have serious third party support so hard core gamers will be on board by the time the wii 2 is here.

and also think has nintendo ever really let us down when it came to a new system... i have full confidence the wii2 will be well worth the upgrade

Forgot to reply to this but here I go:

The difference is that the DSi and DS lite are pretty much the same hardware, they play the excact same games (DS games) and use the same control mechanism. The Wii 2 will be a different console, aside from the fact that it may have the same TYPE of controllers. Your comparison is like comparin the PS2 to the Slim PS2 or the PSP with the Slim PSP. It's the same console, so people won't buy the ld version, they'll just buy thebeter one.

When it comes to a new console, prices vary more, graphcis, controls, capabilirty (hardware overall). Games, etc. This is what I meant.

If they do as many casual games and have a low price it will still be successful
DSNew will be successful if they have a billion versions like they do with all handhelds of Nintendo (VB not included~)
