Should be interesting and I am definitely excited for it. I saw a clip of it and looks good. And gigglemuffinz I am pretty sure they will do at least one more season of Sofia the First. I love that show too and it will be heartbreaking to see it go when it does. But I feel though there is a lot more stories to tell with Sofia the first with some sites claiming that it is renewed for a forth season but then I read it hasn't on another however Doc mcstuffins is doing a forth season so I think they will. Not to mention they haven't even done Frozen yet! Out of all the princesses to appear in the show they haven't done Elsa or Anna yet and they are probably the biggest of all now days. Not to mention the new princess moana that would work well with Princess Lani. Or maybe Pocahontas? that would be a good episode too. They can't end it there's still too much left to tell
------- Update
I just found four episodes of season 4 on IMDB
http://www.imdb.com/title/tt2136138/episodes?season=4&ref_=tt_eps_sn_4 So looks like it will have a season 4.
-----Update
Definitely a Season 4! Just watching the latest episode (S03E21) and they have a new intro! with so many episodes I haven't seen yet and Sofia has new dresses and a new revamped theme song! So excited.
