Apple also generally follows a "don't announce until it's ready" approach (these days it means they have shipping hardware compared to press releases providing perf figures for future products - as long as review sites continue to give free press for future announcements with unavailable hardware this will continue). The one time I recall apple pre-announcing something was the AirPower nonsense, and I'm 90% sure you can't buy that yet :D
