I just came across this discussion today. It's good to see people talk about Han Lue.
I also cannot wait to see the bonus feature which is planned to be included in DVD where I can see more about Han and Dom.
I wonder if Justin can create another spin off film focusing Han as a main character. But Sung is getting older... and it may not be easy for him to keep acting like early/mid 20's. As you may know, if you a a big fan of Han Lue like I am, Han died in 2006. So, Has cannot be older than back then.
I just personally want to see Sung doing something crazy in Tokyo. He does not have to be Han for that.
