There would obviously be many types of people in Skyrim, which amounts to even more types of beliefs. Since the main politics in Morrowind weren't...Really all that interesting in the sense of disposition, adventure, consequences, quests, and rewards; I hope to see Skyrim with a much more fluent system.
Since it is confirmed that the Dark Brotherhood is coming back, and that the Fighters Guild and Mages Guild are theoretically confirmed because of the references of all the Fighters and Mages guilds throughout Tamriel, as well as all the new Guilds/Factions that Todd mentioned they would be adding: This game should be politically heavy.
ALSO:
No bribing faction leaders to let you get in the guild immediately.
No bribing rival faction leaders to like you even though your rivals.
