Looks like 501st will be the last Star Wars book from Karen Traviss after all: Apparently there have been some rumors about this flying around (news to me, but then, I haven’t been looking) and she has confirmed that the second Imperial Commando book is a no-go. The particulars and details – from Traviss’ perspective, anyway – are at the link. (via)
The book was tentatively scheduled for a November 2010 release, and appeared on Sue Rostoni’s schedule post in August, posted only days after Traviss announced she was leaving the franchise.
UPDATE: And Sue Rostoni says:
Karen’s blog was the first time I had heard that she was not going to write the second Imperial Commando book.
I don’t know if we will hire another author to finish the series. It’s rather up in the air at the moment.
Wow… UPDATE 2: Sue goes on to say, “This is really not an issue because Random House hires the Star Wars authors, not LFL,” so not quite as shocking as it first seemed. Still odd.
UPDATE 3: Traviss has a followup blog entry.
