I did like how they showcased some musicians during the Oscars last year.
and, TheGingerBreadMan, the drummer for Wicked is in the pit. I remember seeing him there when I saw the show a couple of weeks ago. And, speaking as a drummer, while the show's score may be viewed as percussion heavy, so to speak, they are all things that are small and can be added onto a drumkit.
I also think that with regards to Broadway and orchestras, they don't need to be in the pit. It's nice to see them if they are but it is not something that I think is needed.
Another thing to consider is that if producers remove a pit from the orchestra, and move the orchestra elsewhere in the theatre (like the basement etc) then they can have an extra row or two of seats.
