If Pewdiepie ends the year with "Year Review" then not only will it further explain the point of the video, but also give Pewdiepie a leaving gift as he slowly loses the number one spot as Most Subscribed. Furthermore, considering Pewdiepie's high sub count, many people are familiar with the youtuber, so seeing him right off the bat would make the audience more comfortable with moving on, forgetting the problems of this year, and moving to the solutions of next year.
