"All I’m doing in stepping away from DC is carving time to tell the stories that have been whispering in the back of my mind for years," he continued. "The last Carrie Stetko story. The next case for Dex Parios. The story of a family’s service to their country, told over two hundred years. The woman in blue. The other one, looking for a soul. The kids who take what they’re told. The killer who guards a park. The soldiers forever at war. The spy with one wound too many."

OK, the first one is WHITEOUT III.  The second one is STUMPTOWN.  The last one is QUEEN & COUNTRY.  The ones in between sound like new concepts??  Regardless, I'll follow Rucka and read it, as he's one of my favorites and an absolute top talent.
From CBR's coverage of Rucka's panel at Wondercon, Rucka mentioned a lot of upcoming projects:

There are a lot of stories in flux for the writer, but hopefully by the end of this summer there will be some announcements. But the writer did go through a quick list of possibilities.

He has one idea for a series of graphic novels, each highlighting a different American war, which would feature one family’s lineage taking part throughout. He’d like to have the same artist for every book, a prospect highly unlikely for any artist to take on, and a project that would take years to complete.

Rucka and J.H. are working on one project that was described by the writer as “’Bladerunner’ meets 'Blake’s 7.’”

There’s an “Arthurian thing” he’s working on.

Rucka and Nunzio DeFilippis want to do a really scary comic book, true horror.

He and Eric Trautman want to do a fun pulp styled comic, something akin to "Betsy Tomahawk versus Nazi Frogmen From Mars" as an example.

And there is a web comic to keep an eye out for at this year’s Comi-Con International in San Diego .
