Im happy its eastern front still and i hope that it focusses really on stalingrad only. So much untold in that topic and a focus on a smaller part of the war means more focus and more possibility for quality. If it will have singleplayer it could be the first game that tells what really happened in that place.
If they would do the entire world war II it would probably be a jack of all trades but a master of none.
Especially alan's knowledge can bring this game to a triumph. I hope that a focus on one section of the war, can really bring forth small details otherwise forgotten.
For me time frame and game does not matter that much, COD4 for me was no different in gameplay than COD2. I hope that even if it were a space marines game, that it will have a different gameplay, objective and spawn system, making the gameplay a bit less forced and a bit more open, and less the same when you replay a map.
