Apple is scheduled to hold a highly-anticipated product launch on October 22, where it is expected to unveil new versions of its full-sized iPad and iPad Mini just before the critical year-end holiday shopping season.
The iPad 5 is expected to be thinner and lighter than its predecessor, while the iPad mini 2 is likely to include a high-resolution "retina" display, analysts says, with some speculating the latter could also include a fingerprint sensor. The color scheme of both iPads is anticipated to match the iPhone 5S with space gray, champagne gold, and silver. At the same event, Apple may also reveal a new MacBook Pro.
"It's not a game changer, but a further upgrade, similar to the iPhone 5S. It's honing the size and specs - we're not going to see anything revolutionary, just an improvement on what we've seen in the past," said Marc Einstein, industry principal, Consumer Telecommunications & Digital Media, Asia Pacific at Frost and Sullivan.
