People such as Mannimarco and Shalidor definitely make an appearance. Divayth Fyr also wrote one of the books in the game, so it is reasonable to assume that once Vvardenfell is added, you'll be able to visit him. (Yagarm as well, probably).

The Tribunal are major players in the Ebonheart Pact, and Jagar Tharn's Ancestor's show us that he wasn't the only Tharn to create major strife for Tamriel.

Most of the Daedric Princes are in the game. (I encountered several during my travels during beta - or at the very least, quests revolving around them).

You get to travel frequently to Oblivion - and not just to Coldharbor (For example, there's a quest where you must travel to Oblivion, killing a few Scamps on the way, and collect the "Unspeakable Sigil" in order to stop necromancers).

It's VERY much an Elder Scrolls game - and to fans of the series, there's a VERY large amount to love about it. There's references to other games and lore all over the place.

That said - it is also in the context of the game itself. There are only EIGHT divines, because it is set in the time before Tiber Septim (and thus, Talos). Likewise, the Third/Septim Empire does not yet exist.
