After watching many gameplay videos of Dark Souls, I'm yet to be convinced that that game is open world, another game Rage looks more open than DS but how open, we don't yet know. Is this a trend where developers are beggining to call their games open world, when clearly they aren't. What do they consider to be the definition of open world? The first example I can think of is Fable 2, even though they didn't actually say open world, they certainly implied it.
The only game I can think of for next year that looks to be open world is Dragons Dogma.
