not things that id like to see, rather things that have already been mentioned and/or confirmed...
--radiant quests --- finally we wont run out of stuff to do for the Mages/Fighters/etc Guilds. Will there be radiant , never-ending quests for other NPCs, say random Joe Schmoe from Village XYZ, to go find 3 ingredients, or escort him to Location X, or kill all the rats infesting his attic (ala Daggerfall Fighters Guild quests, which i loved)?
---Carriage system --- nice alternative to just regular fast travel. Though I dont see the point of using it unless you havnt discovered the locations of the destinations your looking at going to?
--Graphics---- no need to explain this
---radiant AI ---- NPCs wont be clueless, or just stand around, walking in circles. They will appear to actually be DOING things.
---no running backwards at full speed--- i always thought it was stupid people could run any direction, full speed. Cheap combat.
---Daggers , by use of sneak attacks, become useful...
---Bow becomes powerful, not weak was it was in MW.
