I think most fans have guessed it. There is NO new bot stuff cool enough to warrant those extra dollars for seeing it in IMAX. Bay simply wants more and more money, Thankfully, it seems that most guys on TFW have more brains than the sheep on Seibertron. DO NOT GO THE IMAX SHOWING. If ur desperate to go, then wait till all those on Seibertron have seen it to know what the new footage actually is. Funny how Bay gets rich off a film that sucks.... All credit for this movie's success is all ILM and Peter Cullen.
