Here she is, in the state that she's been in for well over eighteen months now. A post on WOSH said that nightspinners, nightwings and firestorms would be nice. There are all here now, and have been available for a few years.
Some of the items from IA 1 made it into the Spaze Mhurine codex. The Iggies got some goodies from IA 2. There is no reason to assume that the 'spinner, 'wing and 'storm will make it into a new Eldar Codex. On the other hand, there is no reason that they should not.
