This sounds made up. We just heard season eight won't premiere for another couple years. If it were gonna premiere in December, we would have seen a trailer or at least some promo material by now. Also, Nick has said nothing about Winx Club for a while now, so the likelihood that they're working with Rainbow so closely again is slim.

And all the previous characters? Absolutely all of them? I find that very hard to believe. Sounds like some fan's wishful thinking.

And there's no way the fourth movie's coming out this summer. Again, we would have seen a trailer or promo material by now, but Rainbow hasn't said a word. The only thing they're promoting right now is Regal Academy and Maggie & Bianca.

I don't think any of this is true. The sources seem questionable, too.
