This is a weird one - I know we haven't seen it in the game at all, but Swen did say Identify was going to be at the initial AMA (See point 12):

Identify is going to be in. And I did indeed mean magical items.

But who knows, long development, maybe priorities shifted / design goals changed.

If you asked me if it's going to be in the game, I'm thinking 50/50
