In an Interview I found there is mention of large scale PvE in the future. This is the section were they discuss it. The translations are a little sketchy though.

Famitsu: Will you be expanding the instance raid in the future?

Yoshida: Instead of expanding we will be planning to adding new ones as the world is going to go through major changes.

Famitsu: Are you planning for any content that will require more than a full party, an alliance?

Yoshida: For alliance feature we are planning to add this along with a content that will utilize this. Right now we’re in middle of battle changes therefore first it’s after a good balanced battle can be done with a party. It’s too simple adding monsters in dungeon with big HP where players just keep on hitting and kill so if were going to do it want to do it right as large scale PvE.

Famitsu: Before it was mentioned that there is something greater than a linkshell, what is this?

Yoshida: We have mentioned company in the past and would like to put this in but before that want players to have strong common goal. It will be after that; that’s the image
