Slow rate of retiring?

I think I read somewhere that LEGO produces around 500 sets per year. It seems to me that would me they would also retire 500 sets per year. I've been tracking the LEGO site closely for a few months and have only seen 35'ish unique sets say "retiring soon". Am I missing something?
