The gaming journalists are returning from E3 and have begun to post their previews of the Pillars of Eternity: The White March expansion. Obsidian released four screenshots from the expansion for them to use:

Here are the previews I've found so far:

The most notable takeaway from the previews is that Obsidian have managed to implement individual stealth, finally bringing that feature up to parity with the Infinity Engine games. You'd think that would have been important enough to mention in the gameplay demonstration. Also, there are details on new abilities, the new soulbound weapons, and even some plot spoilers. Oh, and the new level cap is 14. The High-Def Digest preview says that the first part of the expansion alone will be the same size as Tales of the Sword Coast. We'll see, I guess.
