I would really like for the return of the dwemer or atleast some dlc about it.

No.

Difference is that the Dragons never went extinct. They basically hid for a couple thousand years in areas where people never saw them. The Dwemer literally dissapeared overnight. And I'm not talking figuratively- the unopened dwemer ruin under Mournhold in Morrowind had piles of weapons and armor where their owner stood the second all the dwemer dissapeared!

The only dwemer left, Yagrum, was afflicted with Corupus Disease (allowing him to live to modern times) and only escaped the fate of the Dwemer because he was on a plane of oblivion when the event occured. Vivec himself, a demigod, says that he can't sense them anymore. They're dead, and nothing except Todd himself, in a very big lore-breaking move, can bring them back.

That wouldn't be lore breaking at all all lore says is they tempted to harness a greater power and then poof. That does not at all mean they are dead they merely aren't "here" in no way does that mean they cannot return.

it was a Dwemer Rapture

I'm hoping for something Dwemer-oriented, but I doubt it.

The Dragons returned because Alduin returned. He was able to resurrect them, him being the World-Eater and bringer of the End Times. The dragons were more dormant than dead - they were buried, but they still had their souls within them. All they needed was Alduin to awaken them.

On the other hand, the Dwemer just ... Disappeared. While their reappearance is possible, it could be a bit odd. Why would they return, if they could at all?

Maybe because the power they tried to harness your character fiddles with. Causing something to happen

Also, no. The power that they used, the Heart of Lorkhan, was destroyed in Morrowind by the Nerevarine.

Again Marss we have this http://www.uesp.net/wiki/Skyrim:Arniel%27s_Endeavor an attempt to recreate it and poof. Now substitute him with you, and theres something.

You should read more on the Dwemer. if you think they can come back with anything less than the Devs bringing them back and violated years of Lore ;p

Ive already read everything... with the dagger keening you can recreate the seen as arniel did and most likely dissapear like arniel does. But since your smart youll find a way to escape wherever the hell you are.

All we know for certain is that they dissapeared, and that Vivec, a demigod, is not able to sense them anywhere. Could they return? Yes. Is it likely? Absolutley not- all evidence points to what amounts to the erasure of the whole species on Mundus from existance.

A demigod not a god and there's no proof that they disappeared all at once. Arniel disappeared and the whole race of men didn't go anywhere.

Shor likes Sovengarde, "resurrecting" the Dwemer means meddling in his affairs. The Dwemer still exist, and at least one of them is still likely living, clanking around Fyr and his daughters. The rest of them are slaves to a Daedric Prince, or pieces of Numidium. There may be a few ghosts haunting thier ruins as well.

1. Vivec used the Heart of Lorkhan to acheive his status. He has a fundamental link to the powers that caused the dissapearance of the dwarves. If he says he can't sense them, then, in all liklihood, they're gone.
2. There's no proof that they DIDN'T dissapear all at once either.
3. Arniel wasn't using all the tools, just Keening. He didn't have the heart, either, nor Kargenac's knowledge. Furthermore, he died. The player receives Summon Arniel's Shade (http://www.uesp.net/wiki/Skyrim:Summon_Arniel%27s_Shade#Summon_Arniel.27s_Shade) at the end of the quest.

Yagrum is proof Vivec is mistaken.

Dagoth Ur shall return!

Vivec knows Yagrum is there, he even refers to him when you ask about him

something along the lines of I do not know where the Dwemer have gone, but a better question would be. why is there one left?

We don't even know if Arniel did the procedure correctly- he could be in a completely different place than the Dwemer. He didn't have sunder (or wraithguard for that matter, with no explanation for why didn't instantly die before being able to even attempt the procedure), and the soul gem he used was a poor substitute for the heart of Lorkhan.

I can't begin to describe where your wrong due the topic being in the general section and not spoilers.

Put it in spoiler tags?

from what i understand they are gone for good what they were doing they were trying to be brought back to the time before anything was created and become an aspect all there own. to do this they housed the souls of every last one of them to a bionic body (the brass skin i think its called in the lore page) to achieve immortality. however they have either succeeded or the device to store there souls was disabled and they simply vanished from existence. they were in a war at the time and those two theories were both apart of the lore. they may not be able to come back at all or they may be able to find some way that doesn't completely destroy the lore to bring them back but it is vary unlikely. they were meddling with an elder scroll the object that many think send Alduin forward into time to when skyrim takes place and that maybe that messing with it sent them forward in time as well i mean you do find the elder scroll in a Dwamer ruin and it does say on either 1.6 patch notes or the notes on the DLC ( im not sure which its meant for) something about reading of the elder scroll this could mean a number of things though so don't quote me

Instead of having all of the Dwemer come back, I would like having one or two Dwemer somehow alive. Like plain of Oblivion or a Dwemer machine that kept them in stasis. Preferably the latter since Dwemer technology is really steampunk and I'd like it to stay steampunk instead of having stasis technology all of a sudden.

Like the Mass Effect 3 Prothean, Javik.

it wouldnt be lore breaking, theres nothing saying that the Dwemer can never come back.

Dragons never left, they're everywhere! You must fly very high to see most of them, though. The ones nearer the ground are very hard to see, being invisible.
