He says that Lucas invited himself and Carrie Fisher to lunch during the summer and told them about the plans to do the next 3 films (but said nothing of the sale to Disney). He didn't go into details about the story, but it makes you think the reason he wanted to meet with them was to give them the heads-up.
Alec Guinness was 63 when Star Wars was released. Mark Hamill is 61 now (Fisher is 56).
Also, Fisher posted this short video on her Facebook page yesterday:
