Well I got some information today that I'm sure everyone here will be happy to hear.
Superman will be receiving new trains with a lap bar design similar to that of El Toro at SF Great Adventure. The trains were ordered way back in the spring and will include the onboard sound.
The ride is indeed being painted and crews have already begun the process of cleaning the track with heavy duty chemicals to remove the grime and grease.
Finally the 3+ minute ride length indicated in the press release includes loading and unload time, the track itself will not be altered in any way.
Here is a link to some photos...
