That's not entirely true.The lobby was part of IA's tech, so my guess is that lobbies will be completely different.
The lobby, friends list, server list, messages, profiles, etc were all part of IA's tech. The devs only have the Legions source code. They'll have to recreate the lobby and any other features that IA had (assuming they want to put in those features).That's not entirely true.
Correct me if I'm wrong.
