Orci and Kurtzman not returning to write Transformers 3

Posting on the Don Murphy message board, Transformers and Transformers : Revenge of the Fallen writer Roberto Orci has confirmed that himself and Alex Kurtzman will not be returning to write a third film.

He goes on to state later in the same discussion thread that Ehren Kruger will be taking on full writing chores for the third movie, and assures fans that Mr Kruger knows his Transformers.

The forum had this posted,

"So Bob and Alex is it true. you wont be involved this time round.
It's true.

Sorry to hear that Roberto, really I am. Are we in good hands with Mr. Kruger? Does he know his Transformers?
He does. He really did his homework. He's awesome."

There you have it. Orci and Kurtzman are out, Ehren Kruger is in. Whether that is good news or not probably depends on your feelings regarding much of the humor of the second film (the Twins, Devastator's balls, etc) as most of that came from the minds of Bay and Kruger. As always, time will tell.
