I'm just worried DI will one day go down the path of reposes after repaints after re-releases ala Skylanders. The addition of skill trees to the 1.0 characters was a HUGE thing because it meant that Disney Interactive were willing to give a little back to the fans who have already invested, without making people shell out for new versions of the figures each edition. This would be the next step in that process.
Think about those people who can't afford to buy all the new figures each and every year (myself not included). The upgrade to a character already in their collection would be amazing, not quite as good as a new figure but appreciated none the less. The main issue is that this process doesn't result in much in the way of profits for Disney. But we've seen some good will in the past. I doubt they would make less figures because of 1.0 fixes, more figures is where the money is.
