Dazed and confused.
Saw this on BoLS.
Codexwise: the Necron codex is described as being a minimal updated codex, similar to Grey Knights, crammed into a very short release window.
Models: Unlike Grey Knights there is talk of a new combo-plastic kit for Destroyers which will include the parts for Heavy Destroyers and Necron Destroyer Lords. There is mixed chatter on whether the clear green rod will be replaced with standard plastic.
Timing: Look for these to be coming in Fall.
