Just so you guys realize, I'm entirely sympathetic to the fans (and the artists, to a lesser extent, since they'll find work elsewhere). But I want to emphasize that I see a lot of talk about it being a bad business move, when it's barely relevant (sadly) to Disney.
But yes, basically I'm suggesting (and it's probably worth every cent that free advice usually is, but feel free to pass it on to anybody who might be able to use it) is to look at the actual sales, the potential market, and the sales of similar Disney projects within the UK. Those numbers (and really only those numbers) allow someone to walk into Michael Eisner's office (or Quesada's) to say that, not only are they ditching X pounds of revenue, they're leaving Y pounds on the table by not expanding the push.
More compelling would be a cost breakdown of what Panini puts in and an offer to take over the operation, the Dez Skinn analogy might not be right, here. The Marvel Comics of the 1970s could barely afford to pay their own artists, let alone control a product thousands of miles away, whereas Disney has offices throughout Europe staffed by locals, if they wanted to do business right. As I understand it, it took them a while, but they eventually learned the lesson of the Eurodisney debacle.
The obvious alternative, if the market is there and Disney is creepy, is to pitch a new line to Panini and let Marvel wither in the UK.
