Hi Paramvir,
1. A decision made status before Medicals is NOT a good sign, unfortunately. There was a phase when the Ecas was not reliable and many people got DM without medicals which was reversed in due time. I think in March the Ecas was pretty reliable regarding "DM before Meds status".
But since the reply to your CSE is - Pending review, I would take this as a POSITIVE sign because that was the latest Update from NDVO.
2. During RBVO status we see the following statements:
a. We received your application for permanent residence on xx xx xxxx.
We reviewed your application and sent you a letter on xx xx xxxx. Please consider delays in mail delivery before contacting us.
b. After a while in RBVO stage (4-6m) with the above info, another line is added to the mail which states- ....we started processing your application on xx xx xxxx.
Your ecas will still show RBVO.
Hoping for the best for you.
