It's a great news, Let's hope they come back to the root of Warhammer FRPG, and don't turn in the D&D pitfall about publishing tons of books. When I was young, we WFRPG was very popular because you had all to play in one book, (and great published campaign) while D&D was like 3 almost mandatory books to play.
Also Warhammer is still an incredibly popular setting. At least on my enlarged area, warhammer larp are like the most common setting. (The rest being custom setting), it's a setting everyone knows (even without playing the miniature game) and pretty well suited for RPGs and LARPs
