To me the most interesting bit was about how elves prefer magic of the natural world to arcane magic. This seems to follow one of my own houserules, to some degree, anyway: Elves favored class is Druid (or Wu Jen, IMCs; player choice). Yay!

I also like the return of elves to a more fey-like society. I don't know how they'll manage that if FR is the default campaign world, though as the primary elven sub-races have become LG, IMO.

I think Eladrin may replace Half-elves, though what they're going to do to Eladrin, I dunno. Just my opinion considering we know at least one race will be dumped for 4e.
