Gardner Dozois namechecks me in his list, along with some truly fantastic writers.
At any rate, new or newISH writers to keep an eye on would include: Ted Kosmatka, Vandana Singh, Justin Stanchfield, Jason Stoddard, Lavie Tidhar, Carrie Vaughn, Andrea Kail, Daniel Abraham, Ysabeau S. Wilce, Jamie Barras, Una McCormack, Aliette de Boddard, Beth Bernobich, Jeste de Vries, James L. Cambias, Laird Barron, Sarah K. Castle, C.W. Johnson, Daryl Gregory, Peter Friend, Theodora Goss, Sarah Monette, Mary Robinette Kowal, Cat Sparks, Brendon DuBois, and a LITTLE further down the road, David Moles, Benjamin Rosenbaum, Elizabeth Bear, David D. Levine, Alex Irvine, Greg Van Eekhout, Ruth Nestvold, Jay Lake, Charles Coleman Finlay, Paolo Bacigalupi, Chris Roberson, Paul Melko, and Tim Pratt.
All of the lists include people that make me think, “Huh? Really? [x] isn’t firmly established?” and other people that I’ve never heard of. I’ll definitely be looking for more fiction from all of these folks.
