@Dexter!
Buddy! 2015 mid! lol! i think it will be way earlier.
The KF guys were hired to take command (KF A320 guys) if not direct to command...Therefore once they (KF ATR ppl) get the requisite right hand experience, they will jump left.
That will make space for the right seat wannabees! Also people hired around 09-10 will be (if not already) getting command.
Also they'r getting new 320's every now and then..& the route frequency is being increased too..which requires more crew.
So the requirement of FO's is gonna be more soon. But yea! right now its a WAIT!
