I applied to UT Austin around that time as well and heard back on January 7th. Unfortunately, I was rejected. I also feel like my materials were not as good as the ones I created for later applications. I would try checking the portal directly through MyStatus. I haven't seen anyone get accepted yet so I am unsure what is going on. At the information session I was told that it is a highly competitive program, so I am guessing that they received a lot of applicants.
