Psy, who holds the title of being the artist with the most watched video on YouTube, seems to have a new project up his sleeve!

On the 14th, Psy tweeted,

The photo that he uploaded with a group of people dressed in the familiar blue suit and bow ties and the hashtag #rewind, have people guessing at what this could mean. Perhaps he's hinting that he'll be covering one his previous releases? Or maybe even a Christmas song seeing that the holidays are right around the corner. Any ideas?
