After roughly 3 and a half years of service, the Korean version will be closing its doors on September 26th. This comes after almost four months of no patches of any kind to the game.
The Taiwanese and Hong Kong versions of the game have been going through a similar lack of updates recently, but as of now there's been no indications that either of them will follow in the Korean version's path.
In January of this year, NTL posted an interview
saying that they were still hopeful for the future of the game, and were focusing on its release in the Chinese market. The Chinese version was originally scheduled to go into beta in the beginning of 2012, and even had an official teaser site. Unfortunately, that site
now seems to have been taken offline.
Discussion thread in the Korean version forum
: The person maintaining the Official DBO Hong Kong Facebook page
has addressed concerns that the HK version might be next in saying, "您好，香港紅心辣椒代理的是香港版《龍珠Online》，韓國版本與香港紅心辣椒無關，謝謝。" . Roughly translated, this means "no".
