The villain, even if he is not as strong as Kaguya, has very good reason to smirk. All of his plans are actually in place.
Remember that Akatsuki (this is how I will refer to him until a name is revealed) wanted kidnap Sarada anyway, indicating that he always wanted a hostage situation. The reason for this is simple: Naruto and Sasuke, together, were able to defeat Kaguya (yes, Sakura, Kakashi, and Obito were important factors in this victory.) He needed a distraction to split their concentration on the hostage so that they cannot fight at their full capabilities for fear of harming the hostage. Akatsuki also has a junior league squad of mangekyou wielding, well trained ninja, and quite literally a head full of sharingan (maybe each has a different mangekyou ability, or each is just for izanagi.) I would feel a little confident, yes.
