Many are expecting that the new Mini iPad will have similar specifications to the currently available iPad 2, with just a 20% reduction in overall size. Pricing and availability are appear to be the two main question remaining for consumers. In my opinion, an iPad Mini starting at $199 could be idea...but may not be a reality.
Apple will certainly stick with a 1024 by 768 for seamless integration with iOS 6 and the existing iPad resolution. A big iPhone announcement is suscpected to be just 6 weeks away, it is certainly possible Apple will annouce the iPad mini as well.
