The whole thing is worth reading, but I found this part the most interesting:

Well… I can’t say we’re going to address everyone’s concerns or desires. There are obviously a lot of requests for characters we don’t own but some of the people who have been vocal on forums asking for specific characters, they’re going to get their way. If things work out.
