It has an open API which could be really useful on mobile apps, especially as smart watches and glass (potentially) begin to become more popular. So removing Bluetooth doesn't seem like a huge win. And the beep idea was probably considered (?), but it looks like one of their goals was to remove dependence on hearing.

Make two versions: one without bluetooth ($50-100) and one with (I guess the late bird price is $200). I wouldn't buy the bluetooth one, because I don't plan on using wearables (especially not cycling).
