By my reckoning, which I won't justify with analytics, Wave should hit $20 when about 12mm TPM's are Wave enabled. It could hit $145 when there are about 70mm active TPM's. Neither of these levels are a certainty, but I've got to believe that if Wave reaches 12mm, it will easily exceed 70mm. This number is in the context of 100mm pc sales and 400mm cell phone sales per year.
