Risen 2: The Air Temple DLC Released

I wasn't aware Risen 2: Dark Waters' second story-based DLC, The Air Temple, was slated to be released today, nor have I been able to find a press release from Deep Silver acknowledging the release, but either way, it's now available on Steam. Here's the official overview:
Gargoyles have infested the world of Risen 2: Dark Waters. Explore the mysterious Air Temple to uncover the mystery that surrounds it as you embark on an extensive new quest. Explore and discover an additional island with new characters, quests and enemies with up to 8 hours of additional playtime.

It's worth noting that Deep Silver also promised 5 hours of content for Treasure Isle, while in my experience it wouldn't even take 2 to complete it. Early reports also suggest that the DLC's length is greatly overstated by marketing, so keep that in mind.
