The Last Airbender Premier!?!?!?!?

So, I bought tickets to the 12:01 premier of The Last Airbender, but it didn't have a choice where i bought them (fandango) on whether or not it was in 3D. Is it going to be in 3D at the premier or do movies not premier in 3D?? I was just curious :PP so i know if there are specific theaters and what not. HELP PLEASE! thanks!
