Hi again Vicky!
After medical received, we usually expect "In-process", which means they finally grabbed your application file and took look into it.
and after a month from it (based on timeline updates in this forum) Decision made shows up in your ECAS. And then 1~2weeks from DM, they send PPR email to us.
from the timelines that people talk around here, We (March applicants) can expect "In-process" at the end of August for the earliest possible (it can be delayed anyways from month to year if they found more works needs to be done on your file).
if so, end of Oct 2014 would be best possible PPR timeline for us. So I guess you should apply for BOWP or new workpermit anyhow.
