ES V: Skyrim

I hope they release like a significant expansion DLC, something like Shivering Isles or Knights of the Nine....and not horse armour

They will; there is too much money to be had not too. It's just a question of when will they release it...I'm hoping soonish but it'll probably be a few months yet seeing as the game hasn't been out that long.

Elder Scrolls MMO in May.

Could be ...decent if the last few games are anything to go by.
