This should come as a surprise to no one, because since the acquisition of Lucasfilm by Disney (which also owns Marvel), many have speculated that Star Wars comics would be coming to Marvel eventually, and now it's happening. According to the Blue Sky Disney blog (via Bleeding Cool), the current license at Dark Horse Comics will continue through 2013 after which the contract will expire and revert to Lucasfilm/Disney/Marvel...
"The Suits in the know have determined that no new contracts will be given to Dark Horse after the current ones expire. So all new projects after 2013 will be handled internally by Marvel.
It's not known yet if titles will be worked into the regular line up, or will Marvel create a special branch of the company that deals with Star Wars. It'll take a couple of years for the old deals to work their course, but the stories that Dark Horse have coming down the pipeline will be the last. And you can expect anything new from Marvel dealing with Star Wars to arrive around 2015.
Interesting year for that to happen..."
Can you say Star Wars: Episode VII tie-in comics?
