Hate to burst some people's bubbles, but apparently the BD set is just an upconverted version of the SD masters, with the new OP being the only thing that's in HD.

Now granted, there will probably be less compression artifacts in the BD release because Pony Canyon is throwing more bitrate at the same amount of information, but I'm not paying $200+ for something that's only marginally better than my R2 set.
