ISIL made a deal with the government to evacuate from Yarmouk to ISIL turf. If true, this would as far as I'm aware be the first time the government made a deal like this with ISIL.
HTS is already in the process of negotiation about evacuating from their part of the Yarmouk pocket. This will make east Ghouta the only pocket outside of government control in the Damascus area. Coincidentally, the last batch of rebels left Al-Waer in Homs today, putting that suburb under government control after an amazing 4-5 years of siege.
So depending on the speed of the evacuations, an op in east Ghouta may come sooner than expected. I have no doubt that the SAA & friends can reduce that pocket to Douma, Irbin and Zamalka in a relatively short period of time and then either starve the out or overwhelm them numerically like in Aleppo. After this the AA may be able to make more decisive pushes elsewhere than before, and there's a possibility that we finally see some action around the Rastan pocket. I'm under the firm impression that the path to government victory leads straight through east Ghouta, it's in to the capital and takes a very significant toll on the SAA's capacity at large.
The only thing that could slow this down is if the government really decides to push for Deir ez-Zor, but so far this fabled "Operation Lavander" has yielded in nothing tangible and seems to most likely be another example of SAA vaporware.
