They are very busy with moving local cadets into the A320 and ATR72 fleets and replacing / upgrading expat F/O's on those fleets.
Cadets won't be going on the widebody (except a very small number of cruise pilots for the 777) so I think the 330 and 777 fleets will be pretty stable for the foreseeable. In fact I know some expat A320 F/O's who don't yet have the hours for command, were offered 777 F/O positions (TR at own expense) only a few months ago.
Expat F/O's will be finished here within 18 months or so, but expat captains will be around for a long time yet.
