I've picked up on hints of them using the "Desert like" Khajiit home town as the next setting. I do agree that your logic here is a little off.. Just because the features are much better doesn't mean we can't (or haven't already) thought of ways to improve the game. You are confusing the setting with the features.

Indeed. I mean 'Halo 3' "No we're done continuing the story and game other then Reach."
Ohai Halo 4 5 and 6.

Yeah Bethesda can basically just make a new storyline that leads up to something in the Elder Scrolls series I'm pretty sure.
My only disappointment is the fact that you can't import characters from previous games. (Just not the stats) Ah well...I'll leave that for Mass Effe- oh wait I already beat that and it has no replayability/long lasting stuff...and then I've already beat Baldur's Gate series twice (well, BG1 about 5 times and BG2 twice lol)
ah but yes theres so much they could improve/add.

Just some food for thought. I would like the next TES game to do something comepletely different. I'm hoping for some major catostrophic events to take place, maybe shake Tamriel up a little bit. Maybe a few canyons (like spliting Tamriel into 4 areas and renaming them) or something. Going from province to province is starting to become redundant. Do something different. Something we wont expect.

ES won't cease until we have seen all of Tamriel.

If the next Elder Scrolls has anything to do with the Aldmeri Dominion,it will be set in either Elsweyr, Valenwood or Alinor. They're all Thalmor territory.
Perhaps even Elsweyr + Valenwood combined, since they are side to side, and even then not as big as Cyrodill. It would be so freakin' awesome.
If anything, the Elsweyr mod for Oblivion had me really craving for an actual gamesas title in that setting.

For focused storytelling, Bethesda could revive the Elder Scrolls Adventures line. Anyone else play Redguard? That game had a pretty awesome storyline and solid dialogue.

They need to make a beatiful game set in my, the Kajhiit, homeland

You make no sense. At all. Skyrim has A LOT. There is a copious amount of stuff shoved into that game, and it's almost endless in what you can do and see. But that does not mean there is everything in it. There is only everything YOU can think of. That doesn't mean it's everything Bethesda can think of. It'll take a fair amount of time, and a few other games will probably come before it, but TES VI will come in time.

For now, just enjoy Skyrim for every penny it's worth. And we'll all get to experience the next chapter when it comes.

I have a list of spells not in Skyrim that I'd like to see in the next TES. Balance. Improved UI. An option to feed Stray Dog. An option to tell Lydria to go to her room. Also, the next TES will likely be on a new generation of consoles which should allow them to do a variety of things not possible now.

Not to mention getting to see a new province and its wonders--and to see what happens between the Dominion and the Empire.
