I just read an as yet unconfirmed report that Sapphire Princess is going to join Diamond Princess in the Japanese market next year. The Diamond Princess move has already been announced, although she has been in the Asia market for years; and Crown Princess is coming to the West Coast to take Sapphire Princess' place for the Coastal Cruises; so Sapphire's move to Japan seems logical.
I was sorry to see Diamond move to Asia years ago because she and Sapphire are my favorite Grand Class ships--their design is just different enough to make them feel much more open and spacious than the others. And now Sapphire is going also.
Oh well, I have Royal Princess and Regal Princess to fall in love with.
