Im not saying its proof, there are a lot of sites regarding this info and this seems to be the most speculated because it seems to be what most people want it to be, the title dawngaurd could lead to the
Mythic Dawn
cult being in hammerfell, gaurd as in redgaurd? or not. Its all a guess. but those are the sites i found lising the info. as far as the new lands go, its more than likely to be in a DLC, heres the video again
. that part I Believe.
I do want to say this about the "Land Masses around Skyrim" that people have placed these speculations on: (Ive said this before somewhere.. not sure where)
If you get a chance to look at it, they are not to any kind of Playable scale at all. If you wanted the whole of Cyrodill to be the size of Whiterun + 1/2 of Riverwood.. then sure. Other than that, they are way too small to be playable.
It has to be asked "Why would they put it in there if it is way too small" ..IF it is a playable land one day?
The answer is This. They Need that so when someone climbs a really really tall mountain and look over it, they can see the lands on the other side. It would be horrible if you did that and couldn't see anything there.
(This could support a Flying Mechanic in the future btw) Bethesda is KEY at trying to project the better graphics coming down the road to render their game, so they want to be prepared for their games to be played in such a high quality that we don't even know about yet. That is always how they were.... (Morrowind was awesome, but was even more awesome 3 years after it's release with new Graphic tech, etc)
Now if they make Cyrodill, Morrowind, or Hammerfell in a DLC.. All that land graphic that people make the speculations about would have to be deleted. It would have to go because it is way to small to develope playable content on and it would need to make way for the REAL stuff. I'd love one of these Provinces to be put in as well, but this is not the "Oh OH I Found Something" content that proves it. I understand not everyone can think like the Developers do, but I wish they would just "Think" before they put this crap out on the internet.
And Im not blaming you in that. You are just a Resourcefull dude looking up anything you can find. Those guys posting this stuff to mislead you piss me off sometimes.
Oh and OH... Dragons of Hammerfell? Good God. I wish Some of the idiots might actually play a TES game outside of Skyrim before spamming the internet with stupid crap.. lol good lord, There are Lore Books all over every Game.. I would hope one of the "Internet Scoop-Snoops" Would actually read one before floods the web with dumb smuck lol.
