Overall, it may be very telling that Apple labeled Siri as "Beta" because it could very well be that most of the above could still come true in months and years to come. Apple invested $200 million to purchase Siri, and most, if not all, of the original team from acquisition has stayed at Apple to continue working on the product. Time will tell but I still believe Siri (they still ought to come up with a better name) has a lot of room to grow.
