Maybe he will still be a principal character. The OT had a large group of characters. A number of whom are dead. It will not be hard to add more to the survivors. There is this assumption that the classic characters need to be diminished for new ones to shine. I don't agree with that at all.
I think Luke will have an important role. Lucas named him after himself. There is talk of spin-offs after this trilogy ends the main story. I would think the classic characters will still be important in episodes 7-9. Otherwise it will feel like a different story. With newer characters having even more time in spin-offs.
