I think it would be cool if Bethesda would make addon like Shivering Isles for Oblivion and Blizzard's Burning Crusade for World of Warcraft. With new universe or another planet in TES universe that doesnt look like Earth-landscapes - i.e Morrowindish look like giant Mushrooms , disco world/flat earth , giant gnomes , english humor in quests, demons , aliens - citys and villages with alien like look Morrowind and Shivering Isles citys etc

Absolutely, another daedric realm would be cool to explore imo, don't really know which yet.

Another daedric realm would be great but i think new Shivering Isles with Sheogorath or another daedric realm made by Sheogorath like Shivering Isles but even more crazy and more alien looking would be awesome too.

Another planet isn't exactly possible. The planets in the Elder Scrolls universe are the Divines themselves, the Moons are Lorkhan.

And they certainly aren't going to rehash the Shivering Isles. Sheogorath has had his time to shine. I'd welcome other Daedric realms though, but honestly, I think the Daedra had enough of the spotlight in Oblivion. In Skyrim, it's time to give them a rest and focus on more mortal affairs.

One of the most important things that drew me to the Elder Scrolls games (and keeps me here) has been the series' contiguous, open-world landscapes. I love to explore sandbox landscapes. I disliked Tribunal and Shivering Isles (and Outland, for that matter) because they were not part of the game world. If Bethesda adds new land in an expansion I want it to be land my characters can walk to without going through some cheesy portal.

i think they should show us at least just a piece of another contenient on nirn. its been a decades and no peaks at anything but tamriel. or at least have another race invade another island or something.

Clearly they should make an expansion showing off Atmora (or at least parts of it). It's to the north of Tamriel, so they could even make it part of the main map (like Solstheim), and there's certainly tons of lore it could add involving the Nords and Tiber Septim. Who knows, maybe the upcoming Dawnguard will do just that.

I defintely want another Daedric realm on par with Shivering Isles, but it's kind of hard to pick one. I'm sure they could expand on the lore, like they did with the Shivering Isles. I'd like to think Hircine's Hunting Grounds would be a good expansion, but they already kind of used him in Bloodmoon.

I'd to go to one of the landmasses to the south (like the Summerset Iles) or the west (like Yokuda). However, travelling to one of the planes of the Aedra would be really cool as well. We've seen so much of the Daedra, so why not see some of the Aedra?
