Apple Likely to Introduce iPad Pro and iPad Mini 4 at September 9 Event
While the event will see the debut of the 12.9-inch tablet, Apple does not plan to ship it until November, following late October pre-orders. A September introduction for new iPads is not in line with Apple's past iPad updates, which have come in October for several years running, but Apple may be introducing the iPad Pro several months early in order to give developers time to create apps for the new device.
Apple also plans to introduce the iPad mini 4, a significant update that brings the 7.9-inch tablet in line with the existing iPad Air 2. It appears the 9.7-inch iPad Air 2 may not be updated in 2015, with Apple instead focusing its attention on the iPad Pro and the iPad mini 4 and pushing the iPad Air 2 update back to 2016.
New Macs are also not expected to be included at Apple's September event, and with the iPads being debuted this month instead of next month, it's unclear if we will see two fall Apple events in 2015 as we have in past years.
Today's report warns that while Apple's plan is to unveil the iPad Pro at the September 9 event, the company could choose to delay its introduction until October.
In addition to a larger 12.9-inch display, the iPad Pro is expected to include an A9 processor, 2GB of RAM, a Force Touch-enabled stylus, and perhaps USB 3.0 ports that will support peripheral devices. The tablet will run iOS 9.1, an update to iOS 9 that will debut in November when the iPad Pro launches.
