New iPods and a new laptop model could be on the way at an Apple special event in September, according to Piper Jaffray analyst Gene Munster.

Apple has held such an event for the last three years, and while Munster stopped short of predicting this year's event would see the launch of an iPhone nano or MacBook touch, he did predict some major revisions of Apple laptops. The analyst said Apple could launch 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.

Higher-capacity iPod shuffles and iPod nanos could also be on the way, while the iPod touch may be redesigned and its price lowered, Munster said.

As for a touchscreen Mac, Munster predicted we'll have to wait until 2010. However, a smaller version of the Macbook Air could be available as soon as next year, he added.
