Alright, so I'm certain we all have things we'd like to see in future addons and/or working titles in the Elder Scrolls series, and I'm sure there are many posts related to this topic... But I just thought I'd throw some of my thoughts up here.
To save time and space I'll use point form.

...

- The ability to purchase a bedroll (Or craft from leather/hides), tents (Again; leather, hides), and to build fires using firewood (And a flame spell, or flint and steel?) If the character has the goods, even set up a cooking spit? Better resting in the wilderness, another level for those of us who enjoy the RP aspect.

- The addition of an optional "hardcoe Mode" a la Fallout. Food, drink, sleep, all requirements.

- (Future Title) Bring back Morrowind's painstaking complexities that used to drive me crazy, and force me to spend hours trying to figure some small things out! Lanterns! Candlesticks! Pauldrons! (I always loved the aesthetic appeal of a warrior with his left arm heavily armored, but his right bare. I savoured the little things! They made the game for me, and they're what keeps me playing Morrowind like an addict.

- Longer quests/questlines. I'm guessing I'm not the only person who found Skyrim's questlines far too short. If you can 'Beat' a TES game in three days... Well hell. Yeah, it's an amazing three days, and there is still much to see! But when you've already defeated Alduin it just feels wrong to be running errands for people like some lowly peasant.

- Please, PLEASE fix the appearance of skulls Bethesda. I'll admit that this isn't a game-ender for me, but for a game so graphically intense and beautiful to have human skulls that look, well, fake... They looked better in Oblivion! And likewise in Morrowind! I mean no offense, however - To be honest nearly every game I own is a Bethesda creation (Battlefield 3 is the only game I own that ISN'T made by Bethesda) and I will always be a devout Bethesda fan.

- More recipes for cooking. I want to be able to grill a leek, or bake a potato, bake a pie! Grind flour, get eggs and water or milk from a cow and make some bread! Yes, it's pointless! Trivial! Nothing to do with the game! But it's an RPG! That's the freakin' point!

- The ability to change your character's hair and warpaint after creation. I'm not asking for some Dwemer built contraption that deals in advanced facial reconstruction! Oh no, no... But a barber? An item (Mix charcoal and water, or buy dyes?) to apply/remove the different styles of warpaint. I only include this suggestion because in most of the more recent TES (And Fallout) Games the player was given the opportunity to reconcile their character. Morrowind's "Are you sure you want this to be your character?" bit, a quick check over your skillsets and appearance. Oblivion's sewer exit. New Vegas' venturing a certain distance. Skyrim was just like, "Kay your guy looks pretty decent in this lighting, from these angles. Now name him and prepare to run like hell."

- Being that the next patch includes more cinematic kill cams and the like, I need not complain.

- Silver weapon enhancements! This one seemed a no brainer to me. Yes, I understand that a legendary silver sword would be the bane of any undead you encountered, but hell - silver ingots are relatively rare in comparison to most others. And hell - Silver weapon, silver ingot... Two and two makes four, no?

- Staying on the topic of upgrades... Studded imperial armor? Yeah. I love the look, can't upgrade. Horned Scale armor? D: It's so horny and awesome, but it becomes obsolete so quickly. Imperial weapons? Fur armors? Yeah...

...

I'm going to stop here.

A note to Bethesda; My thoughts here are in no way a negative reflection on my feelings for your games. As I've stated above, I am and will always be an avid fan of your games - The Elder Scrolls series especially. If it takes ten years for the next working title it will be worth it. (Though at that time I'll be thirty-one, and likely too busy with fatherhood to be spending as much time exploring the world of Tamriel. ) All in all? There is NOTHING Wrong with Skyrim. Well, there are bugs, but when is technology ever perfect? The game is amazing, I love it, and if it ever becomes old to me I can always go back to Arena, Daggerfall, Morrowind or Oblivion because they have all retained their replay value - as I'm certain Skyrim will for years to come. Everyone give yourselves a big pat on the back for creating a series that is so full of life! Thank you.

A note to the readers of this post that don't work for Bethesda; If you have any comments, questions, concerns, perhaps your own suggestions/thoughts, please feel free to leave a reply. Thanks,

Basically these, the small things and probably not necessary things is what made me fall in love with Oblivion (first TES game for me)
It amazed me that I could basically move every object off the table instead of them being glued there like in every other game, picking up useless items such as Plates and other Items wondering what they could actually be used for.
I would like them to keep the complicated and almost useless things instead of discarding them in every new TES game, Water walking wasn't really useful but was still awesome, I liked the idea of enchanting Rings to set me on fire o.o

and for hardcoe mode, it'd be useful to me because I sometimes catch myself not Role Playing and turning into the Mindless game trolls

Edit : oh yeah, Separate the dang clothing and armor for Torso and leggings, you already ruined the variety of looks you can have with clothing in Oblivion but getting rid of Belts, Left and Right hand Gloves separate, Left and Right Pauldrons, or worse the removal of Pauldrons.
Stay unique, what other game let's you wear just One glove instead of being forced to wear both
