In a certain post where the new version of Astropad was being released, the developer of the app made claims of new Apple feature. The claim was that the new Apple iPad Pro, which was released in the recent event held by Apple, actually supported the Apple Pencil. According to previous reports and knowledge, the Apple Pencil is a new age pressure sensitive stylus which could only be used along with the iPad Pro which is 12.9 inch big. This new Apple Pencil was actually launched along with the launch of the 12 inch Apple iPad Pro.
Though the claim stated by the developer has not been verified yet, but recent updates from various different sources show that the new 9.7 inch Apple iPad Pro might indeed support the Apple Pencil. It has been seen in the past that Apple has provided certain developing companies with vital secret information so that the companies can create specific softwares to run the secret hardware. Keeping this aspect of Apple in mind, the rumors might finally turn out to be true.
At present, the only concrete information that all have is that the Apple Pencil is only supported by the iPad Pro 12 inch. The main reason behind this is that the 12 inch Apple iPad Pro has parts built in it which supports the unique functions of the Apple Pencil Stylus.
As per the reports about the next Apple iPad Pro, which will be 9.7 inches, will not only have Smart Connectors that will allow the user to attach various powered peripheral accessories, but also have a flash enabled rear camera and quad speakers which will allow the user to listen to stereophonic sound from both portrait and landscape orientations.
