@Automation, you said some good points, but I don't agree with you on all of them. For example - unless you have any official proof of what you just said - I don't see ANY REASONS in why Disney can't just release more Play Sets, figures or power discs than the ones already revealed or showed in the Hall of Heroes. They can simply release a new patch in which will increase the size of the HoH adding the new figures and everything else.
It is soooo much easier for them to just keep doing and updating the game with new content, and still be selling loads of products and getting loads of money, that I don't see any reason AT ALL that it will not happen. And honestly? I hope it does happen. I agree when you say that the game already offers much more content than loads of other games, but this doesn't means that wouldn't be cooler if they keep updating and offering even more.
The options are endless, considering the whole Disney world and characters. And again, I do believe they will keep updating it.
Probably there will be a new Disney Infinity some day, but probably for the NEW GEN. While that does not happen, they will probably keep this one for a looong time, full of updates. (Unless you work for them and they confirmed secretly to you that there are no plans to create more of that
)
