Someone missed the part where they have said they've written SO much in the last year, they are far far ahead of anything we've ever seen, the SGRA content is coming with the major story content update, that could be as early as 1.4 given the hints towards companion heavy content.
Will we see new story, new missions, and conversations for companions with the new level cap?
Not with this first one, no.
It's not happening this year - they're not even pretending it will. How anyone can believe these people at this point is beyond me. Enjoy the game for what's in it now - of course they say they have all kinds of "stuff" written. They even say they've got stuff from the people they fired. Are they going to spend money to produce this stuff? Not in the foreseeable future.
I hate to be a downer but seriously - you're talking about a feature a guy they fired promised a year ago would be in soon after launch and now definitely won't be in even after the first skill cap increase, so at least another 6 months. There's not enough role-playing in this world to convince me they haven't tossed this overboard as super-low priority on their list.
