If they were going to use a re-recorded version, it would of been in the trailer. I think the fact it was the original song points to the outcome that they're just going to use the original. I think this is for the best, since it's the version everyone knows in Japan, it'll be quite nostalgic to hear it. I would be curious as what it'd sound like if Ayu recorded it with her current vocals, but since it's such an iconic song, I don't think she could ever 'out-do' the original. (Probably why it wasn't one of the 10th anniversary tracks)
