Odo and Sisko return, Worf does not. (Worf's back on the ENT-D, although there were some books covering his stint as an Ambassador *obligatory plug for Diplomatic Implausibility here*.)
Yeah, everyone who didn't leave the station in WYLB stays. Except that Ezri's getting promoted to Captain and taking command of the USS Aventine somewhere like four years down the line, but that's what the DS9 relaunch gets for being behind all the other current Trek book series.
Who's Ciara? Kira? Col. Kira keeps command of DS9, gets excommunicated, watches a certain ex-boyfriend get assassinated, all sorts of stuff.
No Dominion War part II.
The Breen don't get mentioned a lot. They just joined the Typhon Pact, though, which is set up as an alliance of six major anti-Federation groups (one of the Romulan factions, the Breen, the Tzenkethi, the Gorn, the Kinshaya, and...ooh, I'll get it in a second...um...the...
Damn. Had to look it up.
The Tholians. Should've had it. But, anyhow, those six races are forming a new entity which is going to be an antagonist to the Federation. But that's four years down the timeline from where the DS9R currently is.
And the Cardassians have had their homeworld devastated, have elected a democratic leader (Alon Ghemor, relative of Tekeny from "Second Skin" and "Ties of Blood and Water"), seen him assassinated, and sent Garak to go be their Ambassador to the Federation. But, again, even a lot of this is looking four years down the line from where DS9 currently is. There's a novel coming out this summer, The Never-Ending Sacrifice, which is going to be all about Cardassia. I'm looking forward to it.
You really should get into the DS9R fiction. It's superb (if you like Cardassians, start with Andrew J. Robinson's A Stitch in Time), and if you really want a reading list, I'd be happy to provide. I strongly recommend them.
Oh, and they do bring new cast on board. Including Ro Laren from TNG.
