Greetings! As has been posted by Devil in this thread: http://forum.perfectworld.com.my/viewtopic.php?t=2820
There is no ETA as of the end of this work day.
The 'major bug' that is preventing the release of the patch seems to be major indeed. Technical and management are in discussion with China and it has been proposed to send a member of the technical staff to China to assist with the issue. Naturally, as there would be costs involved, the decision to send staff over will be pending further appraisal of the problem.
For those checking every hour, it is recommended that you use this time to rest and relax. Checking back just once every few days probably would not hurt.
The Open Beta servers are not expected to open this week, and the odds of a launch next week are not great either. It will be done when it is done. Once the patch is completed and received, it will still have to go through testing on the local test server. After the patch is approved, it will be put on the patch server as well as uploaded to other locations. There will be a few days delay between receipt of the patch and the launch of Open Beta should the patch receive approval.
An announcement will be made on the main website once a confirmed date for the Open Beta has been determined.
Happy Gaming!
