Winx has gotten itself its 3rd US licensee in 10 years, as http://kidscreen.com/2014/10/01/winx-club-and-mia-and-me-fly-into-america-with-earthbound/, fashion licensee Earthbound LLC has picked up the license for not only Winx, but also their fellow Rainbow stablemate Mia and Me. Of course, this still leaves the question of where Earthbound will shop Winx to now...
Hopefully we will get more information on who if anyone will show season 7 in english soon but at least they have not abonded the US.
From what I've read, Earthbound is more into clothing lines and such and less in toys? Maybe Rainbow is trying to stay in the market with the fashion lines, as you don't need to be a fan of the series to buy the clothes.
Maybe you are right
