Before I begin, I will say that, due to work, I've not had time to read every last page of this thread. However. . . .
If I may interject one quick notion, for all the players saying they don't want Star Wars/Marvel/Kingdom Hearts stuff mixed with City of Heroes, it is this:
Even if they own all of these franchises, this does not mean that they will ever mix any of their contents.
While there IS a shot online of Princess Leia standing with the Disney Princesses, that seems to be a publicity shot more than anything else. To date, have we seen ANY attempt at mixing any of the three franchises they already have?
To state that they automatically would shove any or all of the above into the City of Heroes universe is worst case scenario, slippery stope style thinking: a logical fallacy. It might happen as a one-in-a-million shot, but in all likelihood, it simply won't due to all the legal muck it would entail, as well as the potential mess and confusion it would engender among fans of any or all of the individual properties.
