I attended noreast coaster on saturday at sfne and here is a few things they said: The new trains have arrived and the whole ride will be purple, they had to stop painting due to cold weather. They wanted to have it all painted but they stopped to get Mind Eraser done since it will be opening with the park. One of the holdups will be they have to break in the new trains. They have confirmed that media day will be May 21st and the coaster opens to the public on the 22nd. You can see a full update from noreaster.
