He're an excerpt from the Producers Road Map for 2015
"Shadow of Revan was just the beginning. In 2015, we are committed to bringing you more character-driven adventures in the Old Republic universe. You’re going to see a unified story, with a focus on themes that unite our eight classes – everyone is a veteran from the Galactic Civil War with a complicated past and an uncertain future. You’ll see a greater emphasis on your character’s personal history, and on the choices you make."
This kind of paints an ambiguous picture for me with the 'unified story', but I'm hoping the rest of it is eluding to stories that continue the focus on the respective class and not one story fits all class sort of thing. I also want to see more class companion involvement, new conversations for them instead of maybe a single cutscene in the beginning of an expac.
