Search on the LBS Portal gives 179 R1 admits (including people who deferred from the last year). In 2006 according to Angie's post there were 140 admits at the time. Rumor says that applications were up 50% in R1, so adcoms probably had hard time crossing out the applicants. Female rate is 28%.Anyway I know that some people are waiting for acceptance letters from other schools, so there is hope for waitlisted candidates. And good luck to all R2 applicants!
UPD: The number of R1 admits has dropped to 129, so the yield this year is 72% in first round.
UPD2: As Marcelo pointed out, the number of MBA admits has risen to 150 - probably those are the people from the wait list - welcome on board! :)
