Teleportation isn't going anywhere. Anyone who thinks otherwise is delusional. As far as airships/boats go, IIRC it was mentioned that they wanted to give players the choice to either do a cutscene and instant travel, or cs and ride (with possibility of other events happening in route). Who knows what they finally went with. Personally, I hope they offer varying travel packages. E.g. basic cs - transport / upgrade instanced ride (or open world) / adventure package (random mob fights) / adventure package II (chance NM or other special mobs), etc.
