Hyrule Warriors ended to be a good game from what i know, I don't think that people will get some problems. But overall there is no really viable boycott because the game will be out on Arcade and at least just after an year on console, so after more than enough time for people to get a proper judgement on the game without prejudices.
I don't care for Final Fantasy so I can't say I'm interested in the game regardless of TN's involvement. It is interesting, though, to observe the gaming community's views on TN outside the ever-loyal DOA fanbase.
If the reason for this dislike is the fanservice, even always wishing to include it, Team NINJA already showned that in other works they lower the amount of it contrarilty to what happens with their own works. With Metroid Other M this was forbidden them, but Nintendo gave them a pass for Zelda and even if creating sexy characters, in the end the final outcome is pretty far from DoA.
