"Megatron is back —- but you will only get to see him from the long lost past," he writes on his official website Shoot For the Edit.
Mr. Bay explains, "We go way back in time as this movie explains the mythology of the Primes."
He also says that Megatron will be an alien vehicle and "not a tank like everyone suggests." Well, he's half right. The character's Leader class figure displays right on the back of the figure's box that the figure's alternate mode is an "Alien Tank."
While some fans may be happy that Megatron does make an appearance in the film, "sadly he does not [have] much screen time," Mr. Bay writes.
Here's what Celebrity News Service reported;
Los Angeles, CA (CNS) – Director Michael Bay has finally admitted that Megatron will be back in the "Transformers" sequel. The filmmaker originally denied the appearance of the Decepticon leader in "Transformers: Revenge of the Fallen."
He posted on his website, "Okay cat is out of the bag. Megatron is back – but you will only get to see him from the long lost past. We go way back in time as this movie explains the mythology of the Primes. He is not a tank like everyone suggests, but an alien vehicle."
"But sadly he does not has much screen time."
His confirmation comes on the heels of Hugo Weaving's revelation when he was promoting his latest Australian film "Last Ride," saying he has already recorded Megatron's voice.
He told AdelaideNow, "I've already done it. He's [Bay] over in L.A. and we were working on the video split sort of thing and I had this strange conversastion where he seemed to imply it was all a big secret. So there you go – I've given you the secret sccop."
Earlier this year, writer Roberto Orci also confirmed Megatron's appearance during a chat session on TFW2005.com, saying, "Megatron returns!"
