Some info plus answers to some questions:
The starter box is £95
Rule book will be £35
Each Index/Codex book will be £15.
Index books contain a small bit of background, army-wide rules and data sheets for every single unit currently available.
Match Play points are in the Index books.
As far as I could tell, all current factions/armies are covered and payable the same as they are currently. So Tempestus Scions for example have their own section and are a playable Battle Forged army.
PDF rules will be available on 17th; GW/Warhammer stores will have a limited supply of free printed rule booklets too. If you've bought Dark Vengeance since April 22nd, you'll get a rules booklet also, along with all the rules for the models in DV.
GW stores will be doing intros and demos of the new rules from the 3rd (pre-order day).
The models in the starter kit are BEAUTIFUL! Seriously. GW stores should have a handful of examples available to show off as of today.
A few of you have said about expecting free data sheets on release day- where did you see that too..? Can you link a source please?
