Will Wrestlemania 32 be open roof?

Was just watching some highlights of last year's wrestlemania and thought how great it looked outside in the day time, and really gave that 'big event' feel.

I notice the AT&T stadium where Wrestlemania 32 is going to be held has a retractable roof. Do we know yet if it'll be open or closed (or closed at a later point) for the show?
