according to the review of Transformers on IGN.com (http://movies.ign.com/articles/800/800121p1.html), Megatron transforms into an alien jet, a sleek tank, and a cannon. This is the first and only time I've seen tank and cannon mentioned with this movie. Any of you early screeners able to verify this? I know he forms his fusion cannon with his arms, but that's not the same thing as transforming into a cannon. Thanks in advance!
