IMO 30yrs later with EU staying the way it is. The new trio should be Jacen, Jania and Ben. VII could have Jacen flow walking in the past showing his struggles with the death of Anakin and Chewie so it can be a little back story of what happen to them. The new trilogy will be about Jacen becoming the next Sith master due to his struggles dealing with the death of loved ones and the vision of the future he sees and wants to prevent. This future he see's will be the seed for the next trilogy who knows. This all comes from EU it makes sense to us who read it and those who have not well it will be and all new story no matter.
