Hi Abhay,
I live in Faridabad, adjacent to New Delhi. I checked my E-cas last week and there was nothing new. I saw your thread yesterday and you mentioned that you e-cas changed on 25th Jan. So, I thought I too will check my E-cas, maybe there will be an update. So, when I opened my E-cas I saw the update same as yours. It seems like they updated the E-cas sometime on monday. While I was happy that my E-cas got updated I received my Passport yesterday evening itself. The Visa stamp has the date of 18th Jan on it.
So, I believe your passport should be on your way too. Should be there in the next 2-4 days, probably.
