Future of NL and Other Traitor Legions

The Nemesis Claw kill team has been sold out for a while, it seems. I can't for the life of me find any :/ I guess that could be good because 1. Does this increase the possibility of more Night Lords? Maybe a Decimus model??? 2. Similar treatment for other traitor legions, like Iron Warriors, Word Bearers, etc.

What do you think the chances of the above are?

GW wants money. I think it's obvious now there's money in Night Lords, right? What kind of future (if any) is there for NL in 40k?
