List them all here.

Monk can use shields now. (Blizzard caved)

Monk's shoulderpad is huge and floats off of his body. (might want to fix that, Blizzard)

MF is back on items. (noooooo)

Items that are salvage turn into components based on their quality. Normal items turn into Scraps, magic items turn into scraps and Essence. Rare items turn into scrap and an unnamed component (possibly wood).

There are symbols on the minimap of an exclamation point (quest), a chest (stash?), a gear with an arrow (blacksmith), a campfire, and a blue circular object that is possibly a waypoint. The campfire intrigues me, since I doubt it's just decoration to receive a marker on the map. Perhaps it's the in-game interace for finding groups and teleporting to friendly players.

There are two paths leading out of New Tristram. One to the west and one to the North East. It's possible that the path to the North East leads to Tristram Cathedral.

If you see anything else, say so.

The monks resource was swapped out for this video as we aren't quite yet ready to reveal it. The globe shown is actually the current visualization for the barbarian resource, which may still change.
