Just announced today: Rousey will headline UFC 157 in Anaheim Feb 23 against Liz "Girl-illa" Carmouche.
Ronda by armbar in about 17 seconds.
I'm the last guy to be able to evaluate standup stuff but it seems like she is improving rapidly with her boxing. Watch the Kaufman fight - she uses 3 jabs to set up the entry to the takedown, it was well done IMO. She's not going to outbox the boxers nor should she try. She just has to get close without taking damage and then it's a big big problem for the other girl.
