It's not the map per se, it's includedin a software upgrade to the Thalis system. The upgrade has to be tested before it is applied system wide. That's the case with each significant change in the system. There are more upgrades coming and I assume they will all be trialed for a few weeks before they are installed in the entire system. For example, the system will soon offer games. I don't believe they will throw offer them system wide without a limited trial.
