But this could translate to something good or bad. Also it could be speaking about Sasuke and about the path he will take and what he will do.

If it was Sasuke then they would have most likely used his name instead of "that man". They used "mysterious old man" in chapter 670 preview for Hagoromo. And "that person will" for chapter 679 for Kaguya.
