I just bought the R3, and I'm looking at the special features on the discs themselves right now.
Like the R1, it's also a two-disc set, and yes, as indicated earlier, all special features seem to be intact when compared to
those listed at the Disney site. It does not have a slipcase or any inserts/catalogues. I don't know if the R1 will have any of these, though.
If the special features listed at CD Wow! are correct, the Chinese R3 release has an additional CoCo Lee video, while the R1 has a "Reflection" (Spanish) music video.
The Philippine R3 has BOTH the CoCo Lee video
and the Spanish "Reflection" video,
as well as another Spanish language music video for "True To Your Heart."
A minor gripe: You cannot access the
Mulan II sneak preview from the menu screens. The only way to watch this is to eject the disc and start it over again. Seems a bit weird.
