IIRC Apple gave FCP 4.0 owners a free upgrade (via d/l) to 4.5 which added HD editing support. Of course that was before the SarbOx nonsense. I recently upgraded back in August to ensure SL support. I'd be more than a little miffed if Apple introduces an all new upgrade version, not just an update, and charges FCS 3.0 owners anything more that a minor media and shipping fee - $10-20. It's not that Apple owes me anything. Obviously they don't. But it's poor business to play rope-a-dope with customers.
