Pretty much. SasuSakuNaru is pretty much popular in Japan, but Kishi/SP/SJ were looking at the West because that's were Naruto makes a lot of profit. And NH is everywhere in the West (by that I mean a lot of cosplayers, fan art, rabid fan base). And they decided to kill two birds with one stone because SNS/SS also have a large base.
NS was fine in JP, but smaller in the West compared to NH, and Naruto makes money in the West. They will obviously go with the one with more chance of profit.
Still traditional values had a lot to do with the ending, but NH also had a major factor in establishing it. I don't know which would have been canon (NS/SS) if Hinata was never in the picture, but Hinata (her fans) pretty much established the ending we have now.
Wow really?? in experience all my distant friend that lives in the western country never buy their stuff, they read the manga online, download the movie online, and pirate the game. But yeah maybe you right and my friends just a very small fraction of that.
