There's a lot of new footage and information in the IGN 10 hour preview:
-Quest lines are tied to individual quest givers, the black guy in the thumbnail is the quest giver for the main quest(in the portion they played)
-You can switch vocations freely once you've unlocked them
-You unlock vocations by doing a quest for the vocation master
-Vocations level separately(its unclear if this affects all stats or only those that are vocation specific)
-Pawns can point out quest locations and pawns can point out shortcuts if they already did them with their main arisen
-They played Thief, Fighter, Warrior, and Trickster. New gameplay footage
-Thief is the only class with a dedicated dodge ability(so far), Fighter has a stun/execution move
-Devs put an emphasis on travelling long distances, fast travel is sparce and expensive, compared it to going to a nicer restaurant further from where you live.
-IGN journos compared the open world to BotW and Elden Ring where you fill in the map by exploring rather than quest markers telling you where things are
-Your maximum health cap can be temporarily decreased until you do a 'long rest' at a camp or town.
-Quests are "organic", you get quests from talking to unmarked NPCs and characters bumping into you, some story moments are scripted to seem like random occurrences
-No manual saves in the game, the game autosaves to keep you from savescumming different outcomes(ex: you're stuck with the answers you give to the Sphinx)
