@sulkair,
I think july will also be 18. My buddy is in it.
@ManFlex,
No pilots are not required to clean. Our turns are so tight that some guys just do it just to get out on time. I am not sure about the FA's if they are required, but I can ask for you if you are really interested.

Back on topic.
I personally think there will be more than just July and another class.
