It doesn't matter that much now, but if it's true, then it might very well be a concern in the future.
The "next gen" doesn't start until we switch over to next gen software, which will probably happen for most 3rd party developers when the PS4/720 are released. Supposing the Wii U really does have a weak processor, and isn't able to build up a commanding installed base in the meantime, then it's possible we'll see a Wii situation where 3rd parties are skipping it. That would be kind of lame.
Of course, that's all supposition at the moment. Still, it is something to think about if you're on the fence about preordering it.
