I've been speculating recently around what kind of DLC expansion I think'll be released AFTER the Imperial City and Orsinium (which I am intensely excited for, it's just that with the time period and the fact they have the whole of Tamriel to pick from, ZOS have so many things they could pick to work with).
My two main theories are:
Firstly; ZOS will capitalise on the current Nordic/Skyrim-mania and release the whole of Skyrim, complete with second era versions of everybody's favourite cities (with Winterhold fully built before its fall and the ever-popular - Whiterun). Companions? Nordic underground cities? Who knows?
Secondly; an extension of my first theory really, that ZOS will release a HUGE chunk of a previously little-explored province such as Elsweyr or even mainland Summerset? I could even see a Red Mountain DLC with Vvardenfell and the Tribunal of Living Gods! Eek! So many possibilities!
What do you guys think will be their next big expansion? What would be your ideal expansion? Let me know!
