I've just got back from Gamesday and can add a few bits in. I was in Forgeworld seminar two so missed the meet and my phone has died killing what pics I had.
Imperial Armour 9 and 10. Nine is ship boarding, 10 is sieges. Land Raider Achilles. Support for the other chapters and further specific models for Badab will be minimal. Transfer sheets and etched brass for some chapters are likely. Depending on sales we may see shoulder pads. A few more of the special characters may be done. A new Mark IV Ironclad was on show. Tony seemed quite keen to do more Heresy style weapons and seemed struck by the support for close combat arms and chainswords.
Imperial Armour Two reprint and update to bring the rules into line with the current edition.
Imperial Armour 11 Space Wolves versus Eldar. Cold weather conversions for Cadians, some "missing" Elysian troop types. Tony wouldn't be drawn on what the Elysians were as it was still up in the air. Eldar Lynx and Hornet as we've seen. New Aspect warrior Shadow Spectres with flight pack and fire prism style weapons which can fuse together for enhanced effects. Will be sold in squads. Enclosed war walker cockpits plus other addons for the war walkers. Space Wolves special character and possibly wolfy bits. The question of Thunderwolves came up and it seems as if someone will do them, either GW or FW, but who hasn't been decided. That was backed up in the WD subscriber seminar which indicated a willingness to do them but no decision either way. Some minor BFG rules for specific ships.
Imperial Armour Masterclass Volume 2. Some new techniques and reprises of old ones. Lots of pics of lovely models.
Pricing depends on design cost and casting cost. They have little concrete idea how much they'll have to charge until pretty much they have a completed batch in hand.
