To be fair i hope they do go back to old conflicts as it'll mean back to basics of using iron sights, covering fire, flanking and working with your team. There is something good about iron sights and lack of tech and vehicles, it would be refreshing.
As for a WW 1 setting i dont think it would work, as we all know there was a lack of movement during the actual conflict so i don't see it working well for a computer game like BF.
As a side note i would love if somebody did make a game about WW 1 or even go back to say Rorke's Drift or the Crimean War but im a sad c**t and would enjoy playing games like that.
