Let me put it in an even more candid way ...

I dunno how much you do know of worldbuilding and level designing , but making a "Larger" gameworld , would impact nothing on the content of the game because that woudl only be spread on a "larger" landscape , thus would help making the game feel more realistic , more coherent with the environment , finally less crowded but still with lot of things to do ...

In the actual game you cannot walk for a couple of seconds that you step into something , either a wolf , a dragon or a villager or a bandit ... its totally unrealistic and doesn't even give you the time to watch the landscape because you are busy running or fighting ... then a dungeon and a cave every , what ... 20 m? , the barren lands are all but not barren at all are full of life and animals that you do never feel like on a barely populated place... then the size of mountains and regions are so small that forces to make unnaturally even smaller cities , that are actually smaller than outposts ... some of the jarls holds have what .. 4 - 5 houses? this is really ridiculous .....

Personally, I'd like something a bit bigger. Oblivion and Skyrim feel too cramped, and the magic compass doesn't help much (when there's almost always multiple POI markers on it, it doesn't lend much to the feeling of wilderness). Secret undiscovered ruins are more simply ruins that are cleverly tucked away out of immediate view, instead of being out in the middle of nowhere. There's never a fear of getting lost. You zip through regions faster than you can enjoy them on your way to some place.

As it is, the timescale is insanely high to deal with the fact of how small the place actually is. At the very least, I'd like to see the timescale lowered with a corresponding increase in land size, even if the amount of content doesn't change.

I agree the worldspace should be bigger, I definitely DON'T agree that the game should be spread out over multiple provinces. I'd much rather 8 cities with 30 buildings (though that seems a far off dream at this point anyway) than 24 cities with 10 buildings, probably less in fact, due to the extra work required to add new architectural styles, or else have tons of cut and paste cities.

You're the only one here talking out of blatant ignorance. They have been working on it since the release of Fallout 3. 3 years ago, and they did a bit of basic concept work before that. No date has been announced for any expansions.
