Yes I think the time frame will stretch out. The advance by the legit govt/coalition forces means nearly two thirds of the country east of Sana'a is under govt control. This includes the PSA acreage from what I can tell.
The battle for Sana'a if won by the legit forces would mean the Houthis will be confined to the north east corner of Yemen. I imagine that will be the line in the sand for a halt to agression.
The confrontation at Sana'a is being made all the more difficult as the Houthi/Saleh forces ignore Geneva war protocols and place military units in suburban neighborhoods, schools, factories etc. They seem to have at least drawn out some major military hardware from the built up areas as the coalition forces atempt to take the Nehim District nor-east of Sana'a.
