I think they might bring back names that are seen as dated to the late 80s, 90s, or early 00s, because I see a lot of kids enamored by names (and fashions) like that.
Perhaps they may also favour unexpected, "forgotten" names that most people don't really think about and that don't fit into any strong categories. I have seen a few young people express interest in these names that are surprising and refreshing in their random ordinariness. Like....Curtis. or
Maureen.
Other than those ideas, I have no idea what will happen.
