Warhammer Community reports the new Necrons Codex and a new Start Collecting: Necrons set will be up for preorder next weekend (24th March 2018)
The new Start Collecting set drops the Triarch Stalker from the previous set, and appears to replace it with 5 immortals, an Annihilation Barge with Lord on Foot, and what looks to be a second Overlord, making it slightly better value than the former set.
