i think you can still come up with some reasonable estimates though? here are some crude numbers and estimates for june'11

assumption: number of candidates for all exams is consistent.

June 2010 L1 pass-rate: 42% (from CFAI website)
assumption: 75% of candidates who passed register for 2011 L2
2011 L2 candidates from J10 L1: ~32%

Dec 2010 L1 pass-rate: 36%
assumption: 40% of candidates who passed register for 2011 L2
2011 L2 candidates from D10 L1: ~14%

assumption: 2% of L1 passers from 2009 and before register for 2011 L2

2011 L2 pass-rate: 43%
assumption: J10 L1 candidate pass-rate: 43%
assumption: other first-time taker pass-rate: 33%
2011 L2 first-time taker pass-rate: ~19%

personally i think that number is slightly higher. i would've guessed 10%. guess this means my numbers are completely wack!
