Hey, anyone know what's happening to DW marines? Are they in the new SM codex? Or in a supplement like witchhunters? Or are they slated for cancellation? Hate to lose 'em...

I dont believe death watch will get phased out. They are too fluff oriented too get the boot. They should make new models though, if they dont, then yes they might very well be phased out

They are not a supplement to the XH (Xenos Hunters, not Witch Hunters).
They are the Chamber Militant, and as such are an integral part of the Codex, just as Grey Knights and SOB are.
There are a number of threads in the rumours forum discussing what form they will take in the new Codex.

I personally would like to see them become the core troopers of the Xeno hunters.

They are the CHamber Militant. That means they are the core troopers.
It will be like DH/WH, Selections from each category will be DW, plus inducted/inquisitorial Guard and extra "fun" stuff.

Corianis is correct, they are the core troopers of the xenos hunters
I cant wait till they make a ordo xenos army, it would be the coolest

this really needs to be made into a huge pinned topic or something. 2 posts like this in the top half of the rumour mill. how can people not know this by now!
