I wouldn't hold my breath about it, I had faced some problems while signing up and never get any feedback from them. Also, for connecting and transferring some telecom points to my mileage account using their system, it didn't work for three times and nobody bothered to call and check if it worked after all the requests.

Still, I would recommend signing up for any other SkyTeam alliance member since Saudia already joined and you can enjoy benefits of the alliance.
