There is definitely a pit section. Moz played this same venue in 2011 and I was there, and there was a pit that night too.
Yes, I got pit seats during the pre-sale, row C. They are clearly marked with "PIT" on the tickets.
I just emailed the venue for clarification- pit or no pit, seated pit or GA pit. It's an auditorium on a very stuffy university campus so it's not a regular venue that has concerts all the time...
