Talisman was an old favourite of mine in the 80's and early 90's and the new edition will have all new artwork and from what I've heard is looking really good. I was first told about this (and then sworn to secrecy damn them) back in October so am thrilled that I don't have to keep biting my tongue any longer :)
Here's the Full Press Release (Black Industries website)
I personally think that GW's re-entry into the Board Games market has been partially motivated by the success Fantasy Flight Games have had redoing some of the old GW titles (Warrior Knights and Fury of Dracula). It also means that we might start seeing some older titles return as I'm sure GW/BI won't stop with Talisman. Plus they have a couple of decades worth of ideas floating around which they can plunder or return to.
