I dont't know if this info was previously shared, But here I am sharing it. Thanks to a precure fanpage in facebook I got
this article (In Spanish) that says that , in sometime ago while Fresh was airing, they were 2 options: Cancelled or continue.
Part of the article (Thanks google translate) Says:
Screenwriter Atsushi Maekawa revealed during an event that the fate of the Pretty Cure franchise (PreCure) came to depend on the success of Fresh Precure !. Maekawa, principal in charge of writing his script, declared that if the 2009-2010 series had failed, the entire franchise would have ended there.
In his words, "Fresh was a new experimental work and my first time participating in the series, so it was a case of trial and error again and again. If Fresh had failed, the franchise would have ended there. If Fresh was a success, it could continue indefinitely ... That was the big obstacle. "
Maekawa added later that the success of the franchise is due to his fans. "What I want to say is that it's thanks to us that the series has been able to continue. No, it's thanks to all the fans who have seen it. "
