From the Reddit AMA:

Can you tell us anything about itemization? Will magical items be scarce, or will there be a lot to find?

Not like in Original Sin. BG is a different type of game when it comes to loot and item fever. We still want to make treasure exciting, though, and that means a lot of manual work.Treasure has to make sense in the context, and that means hand-placing and hand-creating it. There will be equipment with magical bonuses, but not many - they’ll feel special, and they'll be tailor made.
