Original plan announced in the news in 2010 ish said 500 townhouses for all of the new EK staff. I expect this development probably slowed a bit with the economic crisis.
I would think it's probably correct to assume all the current villas not owned by EK / Royal Family with not the have the contracts renewed due to rising rents with the private villa demand in Jumeirah.
184 of the first batch of villas were sold by Emaar under a big fanfare about 6 months ago. The demand was huge due to a massive shortage of villas in Dubai at the current time. I am not sure whether these were originally earmarked for EK.
However, even if the plan is to eventually have most of EK staff in these villas it won't happen for a long time as mentioned previously - only a few EK villas anywhere near completion.
Still, beats living in the new Al Furjan past Jebel Ali....?
