I don't know about those prices being "competitive" - the Skylanders bundle is around $69.99, and they were smart with the "Portal Owner's Pack" with the release of Giants. I can see this "Disney Infinity" taking off purely for the fact that children must own things that contain their favorite movie characters, but I don't think it'll spread too much into the adult gaming market like Skylanders did. Very interesting read, gave a good bit of insight into Disney's thought process - as for releasing a new "Infinity" every year, that seems greedy, but what do you expect from America's largest money printer?
and skylanders too.
