Apple could reap $164 billion in revenue in 2013, with earnings per share of $40.50, suggests Piper Jaffray analyst Gene Munster. Research firms are already beginning to model Apple's performance for the 2013 calendar year, and Munster notes that his estimates are about 8 percent ahead of consensus on revenue, and 10 percent higher in terms of EPS. The revenue figure bakes in a 19 percent increase between 2011 and 2012, plus another 17 percent jump.
