Actually, I disagree. That's what using the HTML 5 widgets will do.  
If you use the out of the box widgets you'll get key nav, mouse nav,  
look and feel, semantics, etc.

ARIA doesn't try to be HTML. If the role and ARIA attributes started  
driving behavior instead of acting just as an informer to ATs, then it  
would break everything that uses ARIA right now. For a given browser  
it would be unpredictable. The strength of ARIA is that it makes it  
possible to do your own thing and make it accessible. You don't have  
to retest your site for mainstream usage if you add ARIA, because it  
doesn't affect that. Mainstream usage will remain stable with or  
without ARIA markup, and whether or not a given browser supports ARIA.  
It's invisible to everything but ATs. That's a good thing.

Of course not everyone will add ARIA, but it is at least possible.  
That means people can still innovate and be accessible while we wait  
for the next great thing.

- Aaron
