For those who weren't present, they did provided monthly updates couple of years ago as to what updates were being made. A lot of people kept on complaining when the majority of the updates did not show up within the first two weeks. For example: when skill breaks was announced to be coming and people couldn't wait to use minato, they spammed the forums every week asking when the skill break system would be introduced until it was added to the server.

If Oasis stopped doing updates for that reason, it is understandable. However, it is likely that they stopped doing so they don't face accountability if they decide stop a update last minute.

Also, they won't disclose a schedule in regards for events since they want people to spend. if you keep whales in the dark, they will keep on spending at large amounts in comparison if they do have knowledge. In the past, it was easy to predict the typical events as they would show up at least 4-5 weeks but now it's getting harder since those events show up much more frequently now.
