Hey Skyhigh,
Last I heard (a couple of weeks ago) there were about 50 in the pool with another 60 to go through flight screening between then and november. Just call PSA on the details you were given when you went on flight screening and ask for an update - they'll tell you your rough position, whether or not you are competative for a position in the next intake and the number in the pool.
Cheers,
Steve
