More details will be revealed on
Star Wars at Comic-Con, but for now here are a few words from Dark Horse editor Randy Stradley on the decision to go back to the original trilogy's setting. Click the link back to io9 below for the full interview..
"We — the Dark Horse editorial team and the folks at Lucas Books — felt that the time was right to rack focus back on the core characters of the Original Trilogy. It has been a few years since there had been any comics stories set in the era of the OT, as it's called, and the time was just right. Both we and Lucasfilm had ideas for how to return to the classic characters, and all told it took us about a year to work out a plan with which everyone was happy."
