Sources point the Eldar gaining a new codex to augment the three they already have. If rumor is true, then Craftword, Drukhari, and Harlequins will be joined by the newly formed Ynnari.

I’m not an Eldar expert by any stretch of the imagination, but I know a few players that have been looking forward to something of this nature. I’ll keep you posted on further xenos threats to the Imperium, as they develop.
