The official theme song for Hatsune Miku Expo 2018 in the United States and Mexico, “Decade” by Dixie Flatline, now has a promotional video available in 4K resolution at 360 degrees from the official Hatsune Miku YouTube channel. Time to break out your 3D headsets or Google Cardboard and jump in to enjoy the experience!
Note that the wording for theme song mentions “United States and Mexico”, but not Europe. This gives the implication that Europe can expect their own unique theme song at a later date. Only time will tell!
