Is walmart's imax version of transformers 2 optional?

[Valkyr47]

The only place convenient for me to buy blu-rays around here is walmart

I heard they exclusively got rights to an imax version of the movie, however i heard its the same as the dark knight, where its mostly 2.35:1 with the imax scenes mixed in

personally thats what made me HATE the dark knight on blu-ray, and i have no desire to see alternating aspect ratios

if you buy transformers at walmart, is it guaranteed to be this imax version, or do they have multiple versions for sale

also, can you turn off the imax parts or is it like the dark knight

i might just drive the extra 45 minutes to get it at best buy or something

thanks
