It could take place 30 years after jedi I dont see anything wrong with that. Han and Leia Married with kids perhaps. Luke is on a new Jedi council. A new threat rising. It could work with out any CGI to their ages.
Considering he is decades older than he was in the first trilogy, and this trilogy takes place between the first and the last, how are they going to make him younger? CGI character voiced by Ford?
You're confusing the new trilogy with the proposed TV series. The latter is supposed to take place between Episode 3 and 4. The new movie trilogy is supposed to take place later.
"You can cut me off from the civilized world. You can incarcerate me with two moronic cellmates. You can torture me with your thrice daily swill, but you cannot break the spirit of a Winchester. My voice shall be heard from this wilderness and I shall be delivered from this fetid and festering sewer."
