this rules out no media event on the 21st for sure, they wouldnt have one the day after the earnings call..
haven't the media events been well before the earnings call?
The two are unrelated and conducted by different departments w/i Apple. I don't see how it rules it out -- though a second event hasn't been ruled "in" yet. It may not be worth it if all Apple has is a gold color iPad and Retina iMac. OS X 10 features have been well reported already.
