Re: Transformers 3 merchandise
The Leaders tend to be awesome... but I'm SUCH a stickler for "correct scale" that I doubt I ever pick up any other Leader outside of the Leaders I have. I MAY upgrade to DotM Leader Megs once the price drops. I picked up Leader Megs from TF1 for like 15 bucks a few months after the movie came out on BluRay.
I'll probably just get Delux Shockwave.
As for the Bumblebee "arm to gun" model... if it is indeed an improvement I may very well pick it up.
