Hi Eelkon

Just to make it clear - there is no multiplayer in the upcoming patch. The multiplayer update will be available later this year - check the FAQ.
There hasn't really been released any information on which features the multiplayer update will contain, so I'm afraid that I can't answer you question. But I certainly hope that VoIP will be a part of it. Communication is very importent in busy harbours so think we need it.
