I think eventually we're going to see a solid split in mobile vs. non-mobile search, that they'll become two different beasts because one size cannot fit all.

Hmmm... that's what Responsive Design is supposed to address. Have you looked into that, even just a little bit?

it's that focusing on visitors and not on SEO will NOT cut it.

Absolutely right. The basic foundation of traditional SEO still will matter. It's just that they will not be enough on their own, either. These new factors ARE a way to optimize your search rankings, layered onto old school Information Retrieval science.
