The Tempest is reportedly Alan Moore's last GN

In this list of what the UK Guardian calls the best GNs of the year, the following is stated about Moore's latest entry in the League of Extraordinary Gentlemen:

Alan Moore, the legendary creator of From Hell and Watchmen, has said that The Tempest (Knockabout), the conclusion to the League of Extraordinary Gentlemen, will be his last comic. He and artist Kevin O’Neill (who is also quitting the industry) have set their motley literary superleague against Moriarty, Martians and a boy-wizard antichrist in previous instalments, and here Bram Stoker’s Mina Murray, Virginia Woolf’s Orlando and Emma Peel from the (British) Avengers must battle “Jimmy” Bond and a supernatural conspiracy. The digressions long since overtook the main story, but this wild metafictional romp is a fitting goodbye to two singular talents.

Well after the awfully extreme comments he made in recent years about the superhero genre, it'll be fortunate and for the best if he's departing the medium, along with the artist. He's hardly been the best influence on the medium anyway in the long run, and his increasingly leftist stances are making him far less appealing. So, I guess he'll be turning more to novels now, and if he leaves the comics industry behind, that's fine.
