It's not entirely speculation - the analyst observes Apple to have held such an event for the last three years. And while the analyst doesn't expect an iPhone nano or MacBook touch to appear at the show, he does anticipate some major revisions of Apple laptops.
Munster predicts redesigned MacBooks at lower prices, along with a redesigned MacBook Pro.
"We note that the MacBook has had the same design since its launch over two years ago, and the MacBook Pro has had essentially the same design since its launch over 2.5 years ago, which was very similar in design to the PowerBook G4 released over 5.5 years ago," he told clients.
The analyst also expects Apple to introduce higher-capacity iPod shuffles and nanos at the same prices as they currently are - but does not predict significant redesigns in the product. The iPod touch may be redesigned and its price lowered, Munster warned.
The analyst termed a touchscreen Mac as unlikely, but thinks it is in development for launch in 2010. He also believes a smaller version of the Macbook Air is likely in 2009.
