Bruce Silver has a nice article on BPMInstitute.org about the 5 things to like about BPMN 2.0 (he doesn't discuss the 5 things not to like - perhaps material for a future post?!).
OMG votes on the proposal in June, but the history on OMG's voting on BPM-related standards has typically been that it takes longer than I expect for things to get finalized.? I won't be shocked if final approval drags out a bit longer.
Interestingly, 4 of the 5 things Bruce mentions address weaknesses that at least one pureplay BPM vendor addresses already in their product (implementing more than what BPMN 1.0 spec requires).? Let's hope there's more than 5 things to love about BPMN 2.0 - vigorous vendor adoption would be on my wish list!
