I think most of the "daily" quests will be in one way or another part of the PVP zone, where each thing might lead to helping or bettering your sides chances least lore wise.
Um NDA can't talk about the game. Which means to me that it seems you were asking questions that nobody can reply to. "Can we have"
In Cyrodiil, everybody gets leveled to 50, so yes There's been official mention of bounty type quests in that area, IIRC. Which could be interesting depending on how much diversity there is in the targets.
I hate repeatable quests. Only way I'm ok with it is if there's some kind of randomization, like the Radiant quests in Oblivion or Daggerfall's random quests.
In relation to your treasure hunt idea, there ARE treasure maps in the game (some come with the CE), so we know that's in already
they said that they will try to not have quests as plain and simple as "kill this" quests
