$299/$349 is more plausible to me.

Wii U is a faster X360 4GB with a touchscreen controller. I think X360 4GB can be sold at $150 with no loss like MS did at black friday. That leaves $150 for the contoller touchscreen, more RAM and faster CPU/GPU.

My guess is $249-299. If Nintendo wants to make profit it will be $299.

There's no official hardware specs. This is speculations.

I've based my assumptions on the rumored specs at http://en.wikipedia.org/wiki/Wii_U

I know the specs are not finalized, but the final specs won't be that different.

The final specs can be quite different from the speculations e rumors.

 I totally agree with what you just said. The Wii U won't go over $349.99! You guys need to stop thinking it'll be over that, if the price for the PS3 was high for Sony Fanboys then, a $349.99 price will be way too high for Nintendo Fan's. The controller can't be that expensive either and a launch/bundle game wouldn't caust much , too, because it won't take long to develop. Overall I think the price point will be $299.99 at the start and at the end of it's lifetime (or in the middle) it will be around $199.99 to $249.99.

so, so far for most people it can't go over $300 because of their own personal beliefs and desires, not because of any hard evidence... ok

The same can be said about those who believe it will be priced at (significantly) more than $300 ...

While the rumoured components are likely heavily modified, they're based on old hardware that (in some cases) has already been surpassed by low budget hardware. Certainly, the rumours might not be true but there is no reason to believe that the system itself would be particularly expensive.

When it comes to the controller, we know that it is a dummy device that requires the Wii U system to manage all of the processing related to it. While it is (likely) a little more complicated and expensive than this, it should be similar to creating an XBox 360/PS3 controller with a 7 inch resistive touch screen in it. Being that you can pick up one of these touch screens from suppliers on the web in small quantities for $10 to $15 with the suppliers and manufacturers turning a large profits, I highly doubt it would cost Nintendo more than $10 more than current generation controllers cost to manufacture. This will (of course) have a greater impact on retail price than the increase to manufacturing cost would imply, but it would be foolish to assume that Nintendo would have to sell this system for unusually high prices based on the controller.

The evidence is that Nintendo wants to sell a lot of hardware.

At 350 it won't sell.

$350 wouldn't be too bad, especially if it comes bundled with a game ... After all, at $400 the XBox 360 sold well, without the established userbase Nintendo will have with the Wii U and without a bundled game.
