Transformers 2: Revenge of the Fallen to feature weapon Transformers?

According to a post on Transformers Live Action Movie Blog, we may be seeing Transformers that are weapons in the sequel. On a message board featuring producer Roberto Orci the following question was posed: Roberto, will there be Transformers that transform into weapons in TF2? Yes! Well, that's far from a confirmation or elaborate details, but could this really mean that we see Galvatron in the sequel? Or perhaps Megatron transforms into a gun and is used by another Decepticon? One rumor is that the sequel will pit Megatron against Starscream, with Earth and the Autobots presumably in the middle, so maybe Starscream gets a Transformer gun? Guess we'll have to wait and see.
