I know that Siri will be considered Beta when it arrives with my 4s on Friday. I'm really hoping that eventually it will have some excellent customization options, like changing the voice, and calling it by a different name (do you even have to say "Siri" when you use it). Also I'm very excited to hopefully see developers integrate it into their apps. Anyone out there have any ideas on how Siri could be used in a game app for instance?
