Codex in hand, ask away. Things I can quickly confirm:
Canonness Veridyan has a dataslate with rules. She gives out a Precision Shot/Precision Strike bubble to Adepta Sororitas units within 12". Otherwise same as a regular Canoness, but comes with a Power Sword, and she costs 85pts. My first thought - sit her near a unit of Retributors for pseudo-Snipers (ie Rending Heavy Bolters with Precision Shots). Incidentally, the cast on my model looks good - only a very minor bubble on the back of the cloak where you'll never see it. It's also got a 2016 copyright for those interested.
All the armies in the book are their own Factions, with all the implications that carries. The Valkyrie in particular is listed as-is from the Astra Militarum codex (with Faction: Aeronautica Imperialis instead). BUT, Acolytes *can* take a Valkyrie as a Dedicated Transport (as well as Battle Sister Rhinos and Grey Knight Land Raiders). Games Workshop just borked their own FAQ as far as I can tell :s
The Canoness still has the Eviscerator and Inferno Pistols as a wargear option on her dataslate for those who were worried.
The Exorcist Missile Launcher is specifically ruled as a Turret Mounted weapon with 360-degree arc of sight.
Condemnor Boltguns and Immolators have the modified FAQ rulings (ie Condemnor Boltguns only need to hit a unit with a Psyker in it to cause Perils, and Immolators have a Fire Point).
Warlord Traits/Relics are unchanged for both Sororitas and Inquisition
Grey Knights Formation (Demonhunter Strike Force) is 1 Troop, 1 Fast Attack, 1 optional Heavy Support and all units can start making Deep Strike reserve rolls from turn 1 as well as Running and Shooting the turn they Deep Strike. Basically its a slightly different Nemesis Strike Force
Acolytes are 3-9 Acolytes with same statline and upgrade options as before (though Carapace and Power Armour got cut in cost by half). Additionally, any Acolyte can be upgraded to a Mystic with the same No Deep Strike Scatter rule as before. The unit can take Chimeras, Soroitas Rhinos, Land Raiders of all 3 types and Valkyries as Dedicated Transports.
Demonhosts are a unit of 1 - and now have the actual Demon rule too! - but are otherwise unchanged.
Jokearo are a unit of 1, and are unchanged.
Psychotroke and Rad Grenades are unchanged.
