That "medical received" thing is going around, lots of applicants from different visa offices are receiving that same update. I wouldn't get too excited about it yet, I've seen this happen once before this year already. We had about 8 different applications all receive that same update on the Kingston thread (and many others from other visa offices), to date 3 of those Kingston applications are still pending finalization! I don't want to rain on anyone's parade, but I think this is exactly the same thing as occurred then, and it doesn't really mean anything.
