All planned itineraries into the future are speculative, fictional, or speculative fiction at any rate. I'm kind or surprised the Zaandam and Volendam aren't going too (sister "R" class ships to the Rotterdam and Amsterdam, both of which have higher electrical generative capacity and cruising higher speeds than the Zaandam and Vlendam).
Over at Cruise Critic, there has been a lot of speculation for weeks that the HAL brand isn't going to survive.
