I was never talking about the beta patch, but the actual patch.
By the way, I heard this at IGN:
It does have additional content, which is likely where they will justify the monetary requirement.

EDIT: ERROR. While that page is mostly about a patch, it seems as though (upon looking closer) the charge is JUST for the new content.
My bad.
