I did the best I could trying to find people interested in taking over the project. Problem is we don't have much of a community left. It's like a double edge sword. People won't come back to Sonic because it doesn't have a developer. Developers won't take over the project because it doesn't have a community. You would think that at this time someone would want to relaunch a privacy based cryptocurrency with a low money supply. Most people invest based on hype and rumors anyway so someone could focus mostly on website and advertising to bring Sonic back and never even touch the GitHub. My guess is the best thing for Sonic would be entirely new Branding. New logo, new name and new website.
