On the Sunday 3/8/15 after the Open House weekend all of us that attended..well at least I think all of us.. I got one... received thank you email that pretty much said 'to expect to hear from the professors within next few days to continue the dialogue and to offer you a position in their labs'. This sounds to me like an offer is coming....and then at end email also said this one of the most talented group of students they have ever had and that they hope to see most of us in the fall as new students. I think this email seems to be very encouraging, but just not sure if it definitively is suggesting that an offer is forthcoming.
