On the Official Generals Message Boards, Chris (Delphi) posted this message when asked about the status of the multiplayer test.
We have decided on how we will choose people and when it will be released....we just haven't posted that yet.
Better to phrase this would be "community speculation." All the plans, dates, registration process is setup up. We are just waiting on the marketing folks to announce the test.
This is indeed a community speculation phase... let's just hope we dont have to speculate for too long.
