Wasabii has recently announced that the next beta will be another closed beta and has set the opening day for June 2nd at 5PM (GMT +9) with currently no end date (full schedule here). Similar to the first couple of betas, this next one is will also require users to obtain VIP status and will be only be given out for only a limited time. It also seems as if not all of the character or item data created during this beta will be deleted moving into the next one. However, details about this are currently unclear.

For those interested in playing, you should have a look at the Wasabii account creation guide and then the VIP status guide.
