Looks like it's Sotomayor:

I'm slightly surprised, only in that I thought it would be Kagan or Wood. I suppose, though that it's not that surprising: I know there were some questions about Wood's age, and Kagan's young enough that if another vacancy opens up (Ginsburg or Stevens) during Obama's presidency, she can be brought forth as a nominee (with some good non-academic experience to boot as Solicitor General).
ETA: She'll probably sail through the confirmation process; there's really only one controversial opinion (the
Riccio firefighter case), and she made a remark a few years ago about judges making policy. Otherwise, she's got the credentials and a fairly impressive life story.
