While I'm sure there are logistical problems with the comics and novels lining up with pocket's one a month schedule, it can't be terribly hard when Star Wars has been doing it for some 20 years.
Even Star Wars tends to wait. For example, they waited until long after the New Jedi Order
books were finished to launch their Invasion
comic set during that time period. Similarly, they waited until all of the Tribe of the Sith
books were written before they started their Tribe of the Sith
comic. The only exception I can think of is Knight Errant
, which launched both novels and comics around the same time, but they've all been written by the same author, John Jackson Miller.
