They are in negotiation with Carrie Fisher and Mark Hamill to host, although frankly I think that Billie Dee Williams would make a better host. They'll have a weekly guest who will perform skits with the regular cast, including Hayden Christiansen, Natalie Portman, Peter Mayhew and there will be a weekly Ewok feature for the kids. The guest and one of the hosts will do a musical number with an updated version of the Mos Eisly Cantina Band called Mos Notorious Freak E.
