Grey Knights next?

So, today we see word (from an apparently reliable source) that Grey Knights will in fact be next, squeezed in before the Blood Angels-Dark Eldar tandem in the fourth quarter:

Now that Wolves have hit, The next 40k army will be Grey Knights. This release will be codex and data cards only. There will be zero kits for this release.

...... Should be soon. BA and DE could be down the road, but my source says GK. He's been right so many times.

Interesting that there supposedly won't be any new kits, but they don't seem to be lacking much.

One thing not being mentioned much at the moment is the rumoured Chaos/CSM units from a month or two ago. Now with the GK rumour, some are of course suggesting/hoping for a GK/Chaos combo kit, à la Orks-Space Wolves. Would be nice, if true, but highly doubtful.

Can't see it personally. Two marine codexes in a row?

That seems like a strange route to take considering GK don't really need an update. If anything I'd say Blood Angels. (I'd say SoB but they're hated by all of Ward-kind.)
