Vector owns the Japanese Version of Wonderland Online. It seems their contract expired, and possibly because the original makers of the game aren't continually developing the game, Vector decided not to renew the contract, which means the Japanese Version will officially come to an end September 24, 2013.

IGG owns the US Version, and the 2 companies are completely unrelated, so there's no reason for concern. IGG still makes plenty of $$ from this game, and still have updates they intend to release in the future. I'm sure our version will be just fine.
