Many people have voiced against it but I would seriously love to visit Solstheim and see what has changed in the 200 year absensce. I Loaded up bloodmoon for the first time only after playing skyrim and I absolutely loved it.
We may have been there before... but its a completely different place now. Populated with the refugees of morrowind (and hopefully still a large amount of werewolves... though they wouldn't be the Ferocious bloodmoon variety)
Speaking of which. I know we already have the companions and hircines ring (where you can actually see the bloodmoon) But Solstheim would be the perfect place to really beef up the lycanthropy part of the game.
Add more lore, more quests (a place to freaking see them in the wild for once!) and ways to hone your hunting skills (introduction of werewolf perks, maybe taught to you by an old werewolf who has hunted on the island for a very long time.)
But I'm happy whatever it is

Edit: read above comments and just wanted to say, I can understand not wanting solsthiem because it is so similar. It does look just like skyrim if it was made about 10 years ago. But the vibe you get there is really different.
Now, if the DLC does end up being somewhere like Hammerfell/Elesweyer/Blackmarsh I will also be happy about being able to explore new places never seen before. (except arena, and that doesn't count

)
Also I been out of the loop for about a day. Anything I miss in the past 24 hours?
