I only saw mention of it once, and I figure I'll start a thread on it.

From some of the creators of Titan Quest, it's a dark Diablo-like game using a modified Iron Lore (TQ) engine.
I dropped in a purchase/donation already. Looks decent so far.

I haven't bought and played the expansion yet, though since I enjoy Grim Dawn I will most likely get it at some point. More areas, items and 2 new classes will be nice to have. I'm still trying to batter my way through Ultimate difficulty with my soldier class tank character.
I just saw a video on this, though I haven't watched it all myself yet, but apparently there's another expansion for Grim Dawn coming called "Forgotten Gods". It seems to be moving to a desert/Egypt theme along with a new class called the "Oathkeeper". (https://www.youtube.com/watch?v=Isq6payLHMk)
Here's a link to a forum thread covering some information on the expansion. (http://www.grimdawn.com/forums/showthread.php?p=613422)
In the Forgotten Gods expansion, you will journey beyond the bounds of the Erulan Empire, traversing burning sands, lush oases and volcanic wastes to reach the sun beaten ruins of a city with secrets that should never have been disturbed. The flames of a forgotten god have been rekindled, sending ripples through the Eldritch realm and sowing terror even among the Witch Gods themselves.

Along with quality of life features, you will pursue new powers, hundreds of new Unique items and Monster Infrequents and more! Battle dozens of new foes across new dungeons and a new gameplay mode which we’ll be discussing in detail in the coming months!
In short, Forgotten Gods will be another thrilling densely-packed addition to the critically acclaimed Grim Dawn and its first expansion, Ashes of Malmouth.
The best news of all though is that not only has work on this expansion already begun, it’s well underway. We expect Forgotten Gods to release in the second half of 2018!
We are very excited to share more details of what’s coming in the Forgotten Gods expansion, so be sure to stay tuned for future Grim Misadventures as we return to our regular bi-weekly update schedule.
Apparently it's due to be released later this year. There's no listing on Steam yet though so it doesn't seem like there's a specific date set.
I must admit to not having finished the content, or even started, from the previous expansion. Starting a necromancer was fun and playing around with the skills but I can't give my opinion on the length of story/gameplay content as I haven't actually reached it.
