Ok I have read the EDGE article now, not much new info.
They list XBone as a platform
Targets 30FPS on consoles
There are a total of 160 people at RED studios, just 89 of which are currently working on TW3 full time directly. Not counting the engine team
In house motion capture studio in the basement, used for everything except the horse which wouldn't fit through the door
Screens are from a DX11 tech demo using ingame assets, playable build still running on the old renderer aparently, they have still got a year to get it ready I guess
Potions can be drunk during combat like the first game
Some potions give permanant effects, but you can only have one active at a tim, as aparently players saved up potions rather than using them as intended.
Still in active development so subject to change
Rest is old stuff
Main quest chain 40-50h plus another 40-50h of open world content
Trying to avoid "Fedex quests"
NPCs in settlements and towns have rutines and will react to you bassed on your actions
Witcher sense, more in depth than the in TW2, plays into quests and combat (allows you to target weak spots such as cutting off a monster's arm which will change it's moveset and AI)
Facial animation much improved (NPCs much more expressive), lots more animations for combat etc
Combat made more intamate, closer to the book, more bloody, dodge roll replaced with pirouette move, many of the dev team actually fight in battle recreations etc with real swords
