Greetings,
Maybe,they will extend it in the future.
Look what they are doing with Port of Rotterdam,in the beginning you could only sail untill 'Erasmusbridge',now you can go further.
I think it's a good system,to extend it in parts.The reason why i say this is that it's a hell of a job to make scenery.On the end it will get further and further,untill the whole area has been made.
I love this idea.
Marc
