So Mantic games has started a new Kickstarter called Warpath
It is a sci-fi setting and is mostly designed to target disillusioned 40k players. They also do Kings of War, which is their attempt at fixing the mess GW did with Warhammer Fantasy.

The Warpath kickstarter funded in a few hours and in a couple days has gone through quite a few stretch goals. I've taken a look at the alpha rules they have released and it looks pretty good. They actually are working on two sets of rules, one is a bit more abstracted than 40k, a bit more on the "epic" side of combat and they are working on another system that is designed for smaller games. The latter they don't have any alpha rules up for yet, just the basic ideas they are looking at. I think they fixed a few of the things I didn't like about 40k, but I haven't delved too deeply into it to see how I think it might work overall.

I think most of the models they've shown so far look pretty good.
