I can't point you to a specific post (although I'll be looking now), but I've seen some discussion. The main character of the second trilogy is also supposedly a Nicrosil-misting, meaning she (and I think it is a she) can flare other people's metals (like external duralumin) if she is touching them.


I can't wait to see how a society would develop with the various magics in play. I've seen some cool ideas. I think Sanderson even suggested that since Hemalurgy allows you to hear and communicate better with Ruin, kandra could become "prophets" or teachers for Sazed. Marsh might still be around, since he ended up with some atium beads and can learn the Lord Ruler's immortality trick. Koloss will still be around, but they're less aggressive and Sazed changed them so they can breed like a true species.
