Thank you everyone for the kind words. If not for this club, I would not have been able to endure this painful wait.
I had completely given up hope. In fact, I emailed dosa this morning that I should move on from Ross and concentrate on my other apps. 4 hours later, I am booking my flight to Ann Arbor. Just goes to show that we should never throw in the towel. Good news might be just around the corner!
edit : Some info on the remaining slots : I counted 50+ open interview slots between 12/10 and 12/20. There are no interviews on the calendar from 12/21 onwards. So, dont give up. I am sure everyone waiting would get their invite soon.
