X has now released another teaser of the new game. Still no date set. Seems to me like they are fishing for memberships
Users who have active memberships at the time the new 1320 Challenge goes into BETA will be able to carry over their existing 1320 username in the new game. These active members will be invited to participate in the private BETA of the new game.
Both the new and the current game will run concurrently so your existing membership will continue to work in the existing Nitto 1320 Challenge.
Membership details for the new game are still being worked out. The new game will have an entirely different membership structure.
The new Nitto 1320 Challenge will feature a Nitto Instant Messenger (NIM) that will enable you to manage your personal chats and see who is online in the game.
