I think Hammerfell would be the best setting for a new game.

I think the problem with Valenwood, Elsweyr, and the Black Marsh is that their native races are people you either love or you hate.
ALL the races are 'either love or hate' people. The people of Hammerfell even more than the people of Valenwood, Black Marsh and Elsweyr, http://www.gamesas.com/topic/1359866-if-you-could-eliminate-one-race-from-tamriel/.
And most of us couldn't stand having TES: VI be a furry-fetishist's wet dream. No offense to Khajit.
When you say 'most of us', do you have a backup research or something? Because last time I checked, http://www.gamesas.com/topic/1236523-which-province-do-you-like-most/, and also http://www.gamesas.com/topic/1343332-skyrim-community-poll-updated-february-2012/. Hammerfell and the Redguards are doing terribad in polls like these, constantly.
With all respect, 'a furry-fetishist's wet dream' is a very childish way of saying you hate the beast races, it's more like an insult to other TES fans who happen to have other preferences than yours. Black Marsh and Elsweyr, and the possible games set in these provinces, are and will be much more than someone's wet dreams. There are many reasons people like me love Argonians and Khajiit more than humans and elves, and they usually have to do with lore, history, aesthetics, homeland, culture, politics. By trying to belittle us you belittle your own credibility especially in these parts of the forums.
From what I understand, Valenwood is just one huge, thick jungle, Elsweyr is a giant desert, and Black Marsh is a malarial swamp.
Yeah, like Morrowind was just one huge wasteland and Skyrim was just a few snowy mountains. Get real, once Bethesda put their minds and resources into bringing a province alive, it is going to be varied and spectacular, especially on future consoles generation. The hardware is less and less a limitation to design beautiful and detailed landscape. And goodness knows swamps, deserts and jungles are very beautiful.
Conversely, Hammerfell ... the chance to finally include ships or sea-borne quests in TES,
Black Marsh and Summerset Isles are also very good for water/underwater based gameplay.
Wherever they put the next game, how bland or varied its geography is depends only on how it's created at the time, not past descriptions.
Exactly my thoughts. The only limit is their disponibility and imagination. The same with the world scale, it amuses me how often I see messages like 'Elsweyr is too small to have its own game', just because it appears smaller on the map. It can be the smallest on the map and yet the largest in the game, should they decide to make bigger cities, outskirts and distances between cities. The character's speed, the density of hostile wildlife and the topography also play a part in how big the province feels regardless the square miles. That wouldn't mean there is no metric coherence, that would only mean that the hardware has evolved and now allows a better world scale. I wish they manage to make larger maps without losing the level of detail and points of interest, so as to give horses a better purpose and maybe real time carriage and boat travels.
Past descriptions of the provinces (sometimes not even 100% reliable, as they were subjective descriptions of individuals) shouldn't prevent the devs from crafting beautiful and fully explorable lands. The lore itself is a living organism.
