i think they must have perfected the version 3 already by now.  this is a business strategy, waiting for a complete one year cycle to launch a  newer version. maybe add video recording and enhance bluetooth features and 8 MP pix and 32gb storage and a superduper longer battery life?
heck, probably they are now working on version 4 to be launched next year, that could not be cracked by the i Dev Team! hahahaha....
