Of course I hope not but the news I found in this article from the LAtimes.com does not sound promising. Basically the company who owns Six Flags wants to bring down it 2.1 billion dollar debt. They are hoping to sell six of its parks including the one in Valencia. The hope is that if it is sold as a package it is more likely to survive. But they may break it up to land developers.
