A MUST is a cloth Map. Also I would like to have a Dragon figurine. Yeah greatcarbuncle doesn't want that.

I don't want anything lame like a septim coin. That didn't make it feel Oblivion at all. Maybe because
it is weightless and you can have so much, I didn't even give it a second look.
A nice Art Book and fluff in it. I wouldn't mind another Mouse Pad of the map of Tamriel. I used mine up after having it for over 10 years. I don't care for music cd because you can listen to it if you have the PC version and there is always You Tube, so it's really not needed.
So I guess Cloth Map, Art Book is expected. Not sure what else they can add, unless a multiplayer Arena type style to take a break from adventuring all the time.
