Bay has beckoned to 3D, well here’s hoping he might do it right. ie no fuckin conversion shit! As for the plot, Bay has been speaking to USA Today. "The movie is more of a mystery, It ties in what we know as history growing up as kids with what really happened." he said of the plot. And he went on to mention the dreaded reboot word (although it might be just a throwaway comment) "As a trilogy, it really ends, It could be rebooted again, but I think it has a really killer ending."
And in really good news, Bay has said that the comedy element will be gone! Thank fuck for that!
