Our survey shows that Apple will take the wraps off quite a few new products in September and October. From a marketing and sales point of view, too many new products in a short period of time is not a positive thing. An interval of at least two weeks between different products is needed; otherwise the promotional campaign will lack a clear focus and shopping line management will become overly complicated, not good for a satisfactory shopping experience. The good news is that we think Apple is well aware of the situation and is doing what it can to keep each new product's launch as isolated an event as possible.
Kuo believes that Apple will first launch the 13" Retina MacBook Pro and a new 21.5" iMac. That will be followed by the iPhone 5 and new iPod touch. In early October the company will then launch the modified new iPad and a new iPod nano. Finally at the end of October the new iPad mini and new 27" iMac will be released.
Take a look at the chart below for the suggested timeline.
