Yep, I've been waiting for it to be comfirmed, and sadly it's true. Winx Club season four is postponed until further notice. Many suspect that it will be months before we get another episode. The reason is as of yet unclear.
So, where does this leave the production of the English version? Will it also be put on hold? Or is it being produced in other languages right now? We can only hope it's the latter. I don't think I'll be able to stand the wait!
