No that's not what he said. It was in a deeper context regarding to Guildleve.
Komoto: There are many dicussions going on about Guildleve, and there is one suggestion that people be able to enter an instanced area where they are invisible to other players and cannot be bothered by them. However, having many people playing together in the same world is an important part of the game, so we decided to keep everyone interacting in the same field areas. Still, we are thinking of ways to keep users from griefing each other.
If players are at a checkpoint after completing their Guildleve, we would like them to be able to wave a greeting to an incoming party and maintain that multiplayer atmosphere. We feel that it is very important to preserve that warm feeling of sharing a game world with many other players.
Do you think that there will still be instanced zones in some other aspect of the game?
