There have been a couple of "basing" proposals put forward over the years. The most recent one was 2-3 years ago, and the company response, in writing, was a resounding "no". Wouldn't hold your breath on that one.
Anybody considering coming to Dubai must make the decision based on what conditions are at their time of joining. DO NOT expect anything to change for the better. This has all been discussed extensively on the "Ek pilot's meeting" thread if you want more info.
