Six Flags has been interested in the Williamsburg and Florida markets for ages now, and buying up SWP&E would give them direct link into both markets. However it will give them overlap in Florida (SWO and BGT), Texas, and California which they would either sell or liquidate one park to keep the other. I really don't think Six Flags would do it though, since if it does happen they'll be larger than their 2002 self (when they owned a few int'l parks) and that obviously didn't work out well and they sold a lot of those parks a few years later.
