I think we can´t answer your question now (the blu ray wasno´t even released!)

In my simple opinion i think we can´t say that the bd is a crap only because its a one disc edition, the blu ray can hold a lot of data, and there is also bd-live which can grant us very nice contents.

To me the diamond edition of the lion king was the best disney brazilian dvd released, because it came with DTS audio (what were a new in that times of 2003) and interactive games naver seen in dvd before (some players even refused to play it because they were too old to play then, this fact is warned even in the dvd package), but it were not perfect, some mistakes in the subtitles and translation, and some changes they made to the movie, made it a little disapointing.

For now I will let the answer to your question after the bd be released
