Samsung also explained why the next Galaxy Note is called Note7 instead of Note6. They say:
First and foremost though, you might be curious as to why it’s called Galaxy Note7 instead of Galaxy Note6. There are a couple reasons why. First, the Galaxy Note7 will complement our Galaxy S7 and S7 edge, and unify our product portfolio. Second, the Galaxy Note7 will minimize confusion about the latest mobile technology from Samsung, and provide full alignment with Galaxy S smartphone.
