I thought ワンピース was meant to be a reference to the ridiculously popular shonen manga. There were so many cultural/popculture references in the video (star wars reference, yay!) and one piece is so popular in the US and generally Europe anyway, I thought it was there to give a nod to the Japanese speaking people and manga geeks, ymmv. The other thing that jumped out at me re: language was that the scrolling text in the CNN(?) bulletin was Swedish. I think they're meant to be the lyrics to Telephone but my Swedish is minimal so don't quote me on that!
