from rick's bog we know calypso is going to play a part in the series. Personally, i think it is most likely that another male demigod will fall to ogygia. We know it can't be percy, because thats part of her curse and he already made his decision to stay with annabeth.. THat leaves leo, jason, frank, or maybe nico. with leo's 7th wheel business, it would be most difficult for him to stick with the quest, which is why i think it will be him. I'm sure i'm not the only one with this theory :)
