Straczynski reportedly ending his <i>Thor</i> run in September

In news that will surprise few, it appears writer J. Michael Straczynski will wrap up his run on Marvel's Thor in September.

The word broke late Wednesday at ComiXtreme, before spreading elsewhere, that July's Previews catalog includes something missing from Marvel's earlier September solicitations: a listing for Thor: Defining Moments Giant Size #1, touted as Straczynski's finale.

A Marvel spokesman did not respond to a request for comment from Robot 6.

Straczynski seemed to hint in May that his days on the title could be numbered. In an interview about his work on DC Comics' Red Circle miniseries, he detailed his objections to big-event comics and explained the reasons for the success of Thor before adding, "Of course, now that the Siege of Asgard Big Crossover Event is looming before me, I have to do some serious and hard thinking about the future."

Marvel has yet to announce "Siege of Asgard."

Straczynski and artist Olivier Coipel relaunched Thor in July 2007, successfully tinkering with a formula that hadn't served the title or the character particularly well in recent years. Straczynski relocated Asgard to Oklahoma, and sent Thor on a quest to liberate his fellow Asgardians -- including a now-female Loki -- from mortal shells (after their apparent deaths during Ragnorak).

Although well-received, Thor has been plagued by delays, causing Marvel to release one-shots by other creators between issues of the regular series.
