Second: Marvel does not own Transformers, never owned Transformer and did not make the Transformers movie. The Transformers is a wholly owned Hasbro property which current is in movie licensing with Paramount Picture. Paramount ALSO has a deal with Marvel. But the two properties do not collide.
Actually, Marvel
did own Transformers. They were the first to create the comics, in which after they sold the title and all of its licensing or whatever to Dreamwave. but whatever, that's not important.
but ya... I'm not too sure what to think about Marvel and Disney. Seems stupid to me, but I guess money is money, and Disney wouldn't pass up a chance to get a hold of one of the biggest names out there in order to get a bigger flow of dough in. IMO of course
