I was the other MCC admit, and was called by phone this past weekend. Cohort size is 6. There is a waitlist, but I am not sure if those people have been notified. There is an admitted students weekend in a month. I think about 250 people applied this year. Best of luck!
I am a current student at Yale and a lot of graduate students commute into New York, or from New York. It's not very bad, 14 dollars one way and an hour and 45 minutes on Metro-North.
