A new Flyer Supplement and the big News is Stormravens are going to be available to ANY Space Marine army!
Here are the rumors:
Lorizael on Dakka Dakka
My sources say this will be a 70 page "compendium".
It will have updated 6th edition rules for flyers:
Stormraven (now available to space marines and BT) Storm Talon Ork Bomba / dakka jet / burna bomba Valkyrie / vendetta Razorwing & Voide Raven Night Scythe / doom scythe
Also dog fighting rules from crusade of fire and a new flyers scenario. I'm told this book will be a range item and not a limited release.

So there you go. Flyers are now everywhere. And I can tell you that they are a lot less powerful in Apoc (which is probably good!). But still, av 12 Storm Ravens are in my army for good!
