It is not official yet, but according to Katie Miles‘ post in Apple Insider, Piper Jaffray, the investment bank believes that the new industrial designs for iPods and Mac notebooks will be launched in September. The speculation is based on Apple’s tradition of launching new line of iPods in September since 2005.

Also expect the Mac notebooks to be launched in a new avatar, specially so after its tremendous success in the enterprise sector, also because of the additional factors – Apple’s forays into the Asian IT powerhouses – China and India. As analyst Gene Munster, of Piper Jaffray points out:

“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. “To compare, the long-running iMac G5 design lasted three years.”

Now on both these product revamping, there will be an iPhone impact. More iPod’s Shuffles and iPod Nanos. And the iPod expected to be  up to $199. Expect some touch-screen features to be added in the Mac products.
