*This is speculation, please don't bring your notions about how it will never be whatever and blizz won't blah blah blah*
So me and a friend (Phasma) were looking into recent speculation as we usually do, and came across something interesting.
We noticed a "water mark" (yes, they've been there for as long as Outland has been out, and it could just be a graphic) texture off the east side of outlands (circled in red) here:

Maybe it's our minds wanting to think something is there, but it looks like an island of some sort (circled in white) surrounded by smoke, or some sort of gas.
Put against this map we've found (note the island east of Hellfire and the Dark Portal):

You can read about this here:

It seems to us that there might be a good indication that Deathwing might be encountered in either an outlands raid or possibly a CoT raid. Again, this is speculation, we aren't claiming this as fact. What are your thoughts?
Edit:
This is apparently from WC3, but I'm not going to claim it as fact because I cannot source it to anything canon.

Seems to be a whole continent East of Deathwings Lair. Was it destroyed or perhaps it's still there waiting to be discovered?

Was able to find a map of outlands from 2006 and it seems to be there, but with minor differences, and an odd town(which could just be a glitch.)

(this might be "artist" fan work or just a random Oultand map, but the part behind the traced in Outland is from the real map that you can see on your map in game, it's just possible to zoom in closer.) I've found a map from the Chinese(Japanese?) version of TBC that is a lot more clear with the so called landmasses. For people that aren't aware of them, there seems to be some east of Hellfire, West of Zangarmarsh, South and South East of Shadowmoon(Towards the corner of the map), East of Netherstorm, North of blades Edge and Southwest of Nagrand. Basically it's like "outland" is the center of a bigger landmass. or possible floating above another "outland". Although, again, it can just be a watermark or mark for "the nether"
