Where do people keep getting the idea that the entire Western Market is conspiring against the NaruSaku fandom in order to cater to the NH/SS fans? Last time I checked, there wasn't some mass censorship project deployed in order to shut us up.
All the more reason to conclude that even the higher ups in the market don't have shipping goggles glued to their faces. If this book can still be sold in Germany which apparently has a strong Hinata-fan population according to FreakySandra1995, then I don't see why an American market would have to go to great lengths to heavily edit this book in order to please the NH/SS crowd.
It's odd thou that they didn't launch an English translation or at least announce one. The fact that it showed up first in European countries may mean that at one point it will be available in the UK sooner than the US.
Heck maybe there isn't any interest for the book. Regardless of fan perception a lot of technical and economical steps must be accomplished for the book to be launched in a country.
