Dev Question: is a Pacific/Allied sub setting PLANNED?

[Spraug]

Hi there and apologies for asking this question, because I am sure this has been asked before, but I could not find a thread that answers it so... Wolfpack is set to be a co-operative Battle of the Atlantic game, where German submarines try to sink allied shipping. Is there any plan to expand the game to allied submarines as well, for example an American submarine in the Pacific or British submarines in the Mediterranean? And if so will it be multiplayer "only" or single-player campaigns, too?

Thanks
