How many categories?
There are 84 different styles judged at the GABF: http://www.greatamericanbeerfestival.com/the-competition/beer-styles/
And it ranges from things like American Light Lager to oddball categories like American-Belgo beer, Kellerbier, 4 different IPA categories, etc.
The thing that's different about the GABF styles from the BJCP style is that these are always fluid and reflect what's being brewed commercially.
