I think Celebrity would shoot themselves in the foot if they introduced larger than Millenium Class ships. Us loyal passengers do not want bigger, if we did, we would go on RCCL. The Brilliamnce Class is the same platform as Millenium Class but hold MANY more people. Celebrity passengers are looking for the personalized attention & the intimate ships. I for one LOVED the Horizon & will greatly miss her. I fear the Zenith is next on the chopping block.
