From what I heard in a washup a few weeks ago, a lot of the DSO properties are leased so yes, it is possible that some or most are up for renewal soon. However that this will result in people being forced to leave is uncertain - apparently one group of pilots had to move elsewhere when the landlord set his renewal price at 40% more than the current rate (how he was legally allowed to is another matter) and they were relocated as it was above what Emirates are willing to pay. So again it's all down to what landlords' unreasonable, overinflated demands are...
