(Beware the ideas announced in this blog could possibly be spoilers)
From the trailer we can see a new Vampire cult that is in constant battle with the Dawnguard. This means you will have to choose sides and do some epic quests to defeat either side. The main thing we see is that you can become some sort of 'ultimate vampire' if you join the Cult which you will also have to defeat.
From this we can see that you will possibly be able to control bats to kill enemies and it seems that the vampire has some sort of blade coming from his hands which could mean that the combat could be similar to that of a warewolf.
Also if you look in more detail you see one of these vampires suddenly turn into a whole swarm of bats which could be used while actually playing as this 'mega vampire'.
The trailer also shows that you can just go up to people and feed unlike a normal vampire.
From the trailer we also see two main strongholds (One owned by either side), one is surreal and much like that of a old tales of kings - a royal high palace -, and another deamony type stronghold which the Cult may summon or they may even have it in their own vampire type realm like oblivion but its much darker and menacing than Oblivion.
Vampire stronghold;
Dawnguard stronghold;
New realm stronghold;
As well as this we see that the Eldar scrolls will be appearing in the game as a major part since that is what the Vampire cult wants to get to change the universe and plunge Tamriel into darkness with the removal of the sun so all vampires can roam the land and wreak havoc. From this we can estimate that if you choose the cult then this will happen and the earth will be forever darkened but if you join Dawnguard then life will presume and the evil will be vanquished.
As well as this we also see that several new creatures will be appearing which as we see the picture on the left seems to be a kind of gargoyle that will come alive and attack you when your walking around dungeons as well as the Cult stronghold (most likely).
What we also see to the right seems to be some kind of frost Ogre or minotour that will probably be quite hard to defeat if your a low level but should have the same health or more of a normal giant.
As well as this we see that the falmer will be returning in the trailer and with that we may also be learning a lot more about the dwemer.
These pictures suggest that the DLC may be in Skyrim or it could be north of Cyrodiil or maybe Morrowind.
We also see a dragon plunge into water which could suggest that dragons now go fishing or that they are now becoming so comfortable with the terrain that they can produce more devastating attacks as well as attack people trying to swim out of harms way. This could also be seen that maybe dragons can now shout underwater making them much more deadly.
Another thing shown in the trailer is that Crossbows will be used as we announced in an earlier post.
These crossbows will be added in the DLC and you will also be able to use weapons on horseback as seen below which will be added in patch 1.6
As you can see from the female in the image on the left there seems to be new armour. As standard.
As we can see from the image on the right there seems to be some kind of Deamon Horse and not like shadowmere. It seems possible that we may be able to cunjure horses at will and do all kinds of damage. What we also see in the picture is the Cults realm that i talked about earlier that you will probably have to enter for a quest to either defeat Dawnguard or the cult.
As for armour we can see that there will be a lot more sets of clothing and armour for you to collect as well as there will be of course a whole lot more of weapons to choose and I only hope their better than Deadric.
And as well as new armour for your own back, you can -from the looks of things- equip your horse with armour. Oh goody.
Overall this new DLC will be huge because of how much it costs and hopefully Bethesda can keep up more equally or even better than this DLC in the coming future.
