Our friend Stephen Totilo is roaming the show floor at GDC. This makes him privy to a bunch of random information as he passes through the crowds. Here's a blurb about Wii U that he shared.

Wii U chatter was mixed on day 2. A financial analyst told me Nintendo is screwed. Not enough time to be out on their own. A developer told me their fortunes are mixed. Good ambition on Nintendo's part, but, well... it's Nintendo, everyone says it's on Nintendo for the thing to succeed. Same as it ever was. It's almost all on them.

I think we can all guess who that analyst might be. As for the other comments, it's the same thing you always here with Nintendo platforms. It's been like this for years and years, and no matter the success Nintendo has, you'll get a mixed reaction at best.
