Predictions by the sometimes-spot-on, often-way-off rumour site Macotakara suggest that a new, thinner, lighter 5th generation iPad will be released in March.
I’ll make an early prediction on this one: “no way”. I give it a 20% chance of happening.
Simply, Apple loves releasing new versions of its flagship products about once per year. In the past 2 years they’ve carefully “reset” the cycle for both iPhone and iPad to coincide with the Christmas buying season.
I’d say we can predict that iPhone and iPad, along with iPod, will continue with a September/October launch cycle.
