I think Molly Tanzer needs to have a collection out - she's published some incredible short stories that have received much positive buzz, and has a novel coming out this year. She's at: http://mollytanzer.com/
I believe Molly is working on a collection called "A Pretty Mouth," so definitely something's happening there.
Tough, because I rarely read short stories until they're in collections, but with a Nathan Ballingrud collection coming next year some other writers I've been keeping an eye out for collections from include:
Genevieve Valentine -- loved her novel; can't wait for a collection of her stories
Tia V. Travis
Lynda E. Rucker
I'm not sure all of them have a large enough body of work to assemble a good collection, yet, but I'd imagine at least a couple of them have.
I'd also like to see English translations of Mélanie Fazi's collections.
I second Nadia. She wrote a kick-ass Lovecraftian story for Innsmouth Magazine a few years back.
I would buy a collection of Ken Liu's stories in a heartbeat.
I'm astonished there hasn't been one already!
I think she may have one from another publisher scheduled . . .
I'd second Aliette de Bodard and Ken Liu. I'd add Ian McHugh.
And Kaaron Warren has two short story collections that I'm aware of--The Grinding House (published by CSFG) and Dead Sea Fruit (published by Ticonderoga).
I don't know if she's got enough stories, though?
I love that so many people are suggesting so many women writers! :-) And I totally second Cherie Priest.
The answer I usually give is Genevieve V., Veronica Schanoes, and Becca De La Rosa.
Ken Liu would be a good choice, if her can take time out from producing a new story every ninety seconds to put a collection together.
Maybe Desmond Warzel; he's made some noise in the Million Writers Award and Micro Award, his work last year in Triangulation and Daily Science Fiction seemed to be well-regarded, and he has a bit of name recognition from that time-travelers' wiki story that viral a couple years back...
Lavie Tidhar, to name one. A bunch of collections appear to be in the pipeline that would obviate some other choices. Laura Anne Gilman?

She has one coming out this year from me, already.
Kathe Koja wrote several stories I liked. But she did have a collection many years back. Invalidated due to that? I'm all out of ideas now (and people like Orrin Grey & Molly already have collections coming out, so I'm skipping those). :P
I'm not as current with Kathe Koja's work as much as I'd like but the previous collection was fifteen years ago. The big question is whether or not there's enough recent material. I'll sic Paula on that avenue . . .
I'd say some combination of the following:
David Niall Wilson
They've been doing some interesting things over at Crossroad Press, including several short stories/novellas. It'd be very cool to see those and others collected.
