In the long run I think we're more likely to end up with a full js-based styling approach that, similar to JSX, might look like CSS but really directly styles individual nodes and 'manages' them.

But this is probably quite a ways off.

The tricky part is handling things like hover states and pseudoelements. I think scoped CSS and shadow DOM (and other new techniques) will probably be the key to making this work long-term.
