The Chinese report cites industry sources as the origin of this piece of information.
It was only less than a week ago that Apple settled its prolonged spat with Proview over the “iPad” trademark in China by coughing up $60 million. Apple had already completed the formalities required to gain regulatory approval for the iPad in China, which suggests that the only hurdle the company had to tackle was the Proview iPad trademark dispute.
PCPop’s report estimates the price of the 16GB (presumably WiFi) iPad to be 3688 yuan (~$580).
The 27th July launch date gives Apple less than a month to prepare for the Chinese iPad launch, if this report does turn out to be true. Apple has to be fully prepared with adequate stock to avoid the issues it faced with the launch of iPhone 4S.
Apple views China as a market where its future growth lies, as evident by the China specific features introduced both in OS X Mountain Lion and iOS 6.
