New intel shows the model with the original stats we had earlier this week from our own sources here on Faeit 212. Lady Atia confirms them here with pics on Bolter and Chainsword.

There are no 40k rules
Regarding the other dataslates that we have seen this week, Lady Atia is on it (thankfully, and its frustrating that several other locations are not crediting her).
Question about these
Wait, so there ARE 40k rules and they ARE official and they ARE locked behind a £100 pay wall for a single model?

No. From what I got told, it's just a thing made by a store and shared, similiar to the BaC formations who are not official, but can be used by the store's who handed them out. Your store makes the rules. But they aren't done by the Citadel Design Team afaik.
