GW made an announcement last week that the game will be released this Christmas:

QuoteTalisman is back! Get ready to return to a world of magic, monsters and heroism and write your own story in this classic board game, out in bookstores and hobby shops across the world this Christmas.
Talisman pits 2-6 players against one another in an epic quest for the Crown of Command, travelling through mysterious lands and magical realms in pursuit of knowledge, power, and of course, a powerful talisman of their own. With hundreds of adventures and a range of expansions, no two journeys through the lands of Talisman need be the same; venture into distant lands and meet mysterious travellers – only the very strongest will pass through the Portal of Power.
Talisman will be releasing soon, alongside six expansions with new realms to explore, new enemies to battle and new power to unlock; dive into the depths of The City or brave the lair of The Dragon. However you want your adventure to be, you’ll be able to start it very soon – Talisman will be out in time for Christmas this year.
Although other sources indicate that it will be out by October/November: http://www.toynews-online.biz/news/read/coiledspring-to-distribute-games-workshop-s-talisman-the-magical-quest-game/048937
