I have reasons to doubt the authenticity of the "contract". I don't believe that the real contract would be floating about the Internet. Another thing is that the document continues to use MCA. I could be wrong, but I don't believe that NBC/Universal is a part of MCA anymore. Furthermore, this "contract" seems to imply that it is between Universal and Marvel. If the parks are sold to someone new, this contract would no longer be valid. Also, it would be in NBC/Universal's best interest if Comcast would buy the parks, however, that isn't guaranteed. As someone put it in another post, why would they pay $2 Billion to basically keep something exactly the same. I've found by observing other such deals that no news usually means trouble. We'll have to wait and see I guess.
There is literally no assertion in your paragraph that has any accuracy or grounding in fact. I could go one by one and refute them, but you could do so yourself by reading through the thread. But to reiterate, everything you said is wrong.
