So, they are “tinkering” with it then?

Disney Thinks Tinkerbell Movie is Too Childish
Walt Disney had planned to release The Tinkerbell Movie in 2007 but after reviewing completed portions of the film, the studio has decided to send the animators back to work with a new launch date of 2008 or 2009.
According to the Internet Movie Database, the studio had wanted the direct-to-DVD release to appeal to the ‘tween girl crowd but the movie skewed too young, towards kids aged 4-6.
This posed a serious concern for Disney as they were planning on launching a Tinkerbell franchise for the ‘tween girl audience with several other direct-to-DVD movies over a three year period.
