i was wondering the same thing. you beat me to it...lol. on my 2005, i purchased some wiper blades that were guaranteed for life. they were made out of silicon. i never had to replace them either. my wife needed some new blades and i can't find them in the store. i bought the previous set from walmart. i don't remember the brand name, but i can't seem to find them.
anyways, what are you guys using? oem? bosch? michelin?
