For everyone, the McCombs admissions blog is updated. Biggest items include:
"The McCombs School of Business and the MBA Program Office will be closed from Friday, December 24, 2010 until Monday, January 3, 2011. Please contact us with any questions you anticipate before the 24th as we will not be available during that time to take your calls and emails."
and
"Additionally, if you are invited to interview as part of the application process, we recommend that you interview with an alumni in your city and plan to visit campus once school is back in session for the spring semester."
No word on the expected timeline for interviewed student, which seems to be the main question right now.
