In the 90's, yes. Today not as much. It could be argued that Simpsons is a bigger money maker than X-men and F4 rights (which are the only ones at stake), but I think that's a stretch. But your larger point is still valid, the guys at the top do not care about individual licenses, that is incredibly insignificant in the deal. So when discussing what will happen you have to examine it on that level. With Fox Studios not only are you getting a great resource for future films, but a huge backlog of film and tv rights the combine value most likely exceeds Marvel current value. X-men and F4 rights, are not informing any of these decisions, even though it's the only part of it I personally care about.
