What different kinds of traps do you guys want in Skyrim? e.g. trip wires, log piles ect!
Since it's been confirmed that the PC will be able to cast magical runes and glyphs on the ground, I expect that NPC spellcasters will be able to do the same.
We will likely see enemy spellcasters using magical glyphs that cause frost, fire, electric, paralysis, poison, possibly telekinesis or force damage.
