This was from Wargames Illustrated:
The Historical Wargamers Group, in association with Wargames Illustrated, held another successful event at Warhammer World on 24 - 25 October, WAB players from around Europe did battle across several campaign settings and attendees were treated to a bonus surprise appearance when Warwick Kinrade of Forgeworld demonstrated the forthcoming Games Workshop World War II game.
Warwick ran through a game in which a British Battlegroup stormed a German held position in Normandy circa 1944 - the British sector in Normandy being the focus for the rulebook. The game is designed for 20mm figures although it will work equally well with 15mm (adjustments will be necessary for 28mm). Interestingly the game seemed to owe little to the well-known Warhammer game system.
The game is still work in progress with a release date of "next year - hopefully early on" planned. The core rulebook will be supported by further supplements, which will include more army lists and (further down the line) more threatres of the war).
***Well There you go.... sounds like another Game system from GW
I don't know if it will be a Main line or a FW/BL/SG release though....let the speculation begin.
