I think it will be a new class. The Carnival Corp CEO said there wouldn't be any newbuilds after these (Jubilee -2023, Seabourn Pursuit -2023 Queen Anne -2024, Sun Princess -2024, Sphere 2 -2025) until at least 2027, and that's stretching it. From there it will have been 4-5 years since Jubilee and 7-8 years since Mardi Gras so I think the next new build would be a new class.
