Gen Con posted the current catalog of events (as of 4-12-09) for Gen Con 2009. It is a massive Excel spreadsheet (or .csv file) that lists all the events currently planned for Gen Con 2009. Even now, months before the event, the list is almost too big to easily search. Happily, the spreadsheet has filters built in already. It makes it much easier to limit the rows displayed to what you are seeking. The catalog is a bit buried in the Gen Con site, but here is a direct link to the download page.
