The good news: Trailer Addict has snagged what appears to be an exclusive sneak peek at a brand new trailer for the forthcoming Harry Potter and the Half-Blood Prince.

The bad news: The trailer is low quality, snagged from some sort of television preview, and has very annoying Japanese voiceover.

Hopefully this trailer hits the US in glorious Quicktime soon and with better voiceover. It's a shame that many international audiences never know the power and the glory of the late Don LaFontaine: The Voice. Anyway, we've embedded the bootleg trailer below. If you'd like a more in depth look, a Japanese Harry Potter fansite snagged stills from this trailer a week ago, but they are just as poor quality as the video. I guess these will hold me over.
