Now I know Wikipedia is not a definitive source of info, but if you look at the games workshop page in the out of print, republished section, it mentions Talisman Warrior Knights. So is this a version I've not heard of or possibly the title of the next release.

as I said, it is Wikipedia so it could all be a load of tosh

Warrior Knight was a game released in the late 80's I think so this could just be a typo combining them both

Thought it might be too good to be a scoop!
