I have the following rumors to add.

Nids to get valentine love, crons to get leap year love.


There are many more nid kits that are done, some no one would expect. However, not all will be released. Others may be single releases later.

4 plastic kits
4 finecast

After the wave there will still be some model(s) not represented from the codex.

Old models getting finecast makeovers.

If you don't know, you haven't been paying attention.
