Agree with above. CX has a top 3 F product that doesn't need a major overhaul. Some F/Suite cabins have doors but there is enough privacy not to need an actual door, which some may find claustraphobic. They may update the IFE or redo the seats with leather or another material down the line as they show more wear but I don't think a complete redesign is going to be needed for the next 5-7 years.
