well, obviously, it would be that the "objective-driven" campaign will be a polished version of SH4's. I highly doubt they will go back to what they did in SH2, that was long ago and now things are totally different.
I'm looking forward to what they come up with. My only fear is that you are dispatched to various battles. I would like to see SH4's objective system, optimized for U-boats, like starting weather stations in the arctic. Or maybe having the choice between helping survivors of a sunken merchant, or leaving them stranded. I would like to see a difference between "reputation" and "renown." Reputation is for sailors, renown is for admirals. sink a BB, get a few hundred renown, help the sailors, earn a hundred reputation. the more reputation you earn, the easier the british may be on you, we can all agree it is easier to kill a cold-blooded captain, but if they can identify your sub, they may capture it, capture you, let you surrender, or let you await your trials at Nuremberg. your amount of british reputation would be kept secret, while your Kriegsmarine reputation will be shown. having a good mix between rep and renown allows you to get better crewmen, more renown lets you get sub upgrades, and more rep lets you get longer leave times if you so choose, maybe even let war correspondents on board
