According to en.wikipedia.org/wiki/List_of_DHX_Media_programs, under the Cookie Jar list, it is rumored that Muffy will be getting her own spinoff in 2013.

If this turns out to be true, then it's probably why they put 9 Story in charge of the main show's animation for the time being. What do you guys think about this?

I have to look into this. Until I find more I will take this as a grain of salt. Since this came from Wikipedia it's usually not a reliable site, but there are those times they are actually correct.
