User blog comment:Jimeee/Skryim DLC Details Leaked in 1.5.26 Update Files - The Snow Prince!?/@comment-4977109-20120428135828/@comment-5060344-20120429111107

I think it would be awesome if you used an Elder Scroll to jump back into a time when the Dwemer where still around and the Falmer were still their own civilisation. Kind of ridiculous but given that you use a dragon break to learn Dragonrend maybe it could work ( in practise I'm not sure how it would work, maybe another previously sealed Dwemer ruin pops up on your map and you find the dragon break inside). I really doubt that it will be that but it would be cool.

More ruins like Blackreach would be cool but I would also like to see some more of the Dwemer's scientific capabilities. An observatory maybe or a factory for producing all of their various constructs. Hell there were even plans to build a Dwemer airship at one point so i guess there are quite a lot of possibilities. Except there is no mention of the Dwemer in the leak so in all probability none of this will happen.

On the crossbows thing yeah, still not sure about them in terms of gameplay, but given that Dwarven Spheres wield crossbows that are easily carriable for a human, maybe you just find one lying around. If the cossbow was integral to the DLC like the pulse emmiter was for Fallout New Vegas's Old World Blues then that would be interesting. Also pistol size crossbows that are dual wield-able would be awesome.
