The 12.9-inch iPad Pro has been detailed in full ahead of its unveiling

The iPhone 6S and the next-generation may be the most anticipated devices that’re expected to be unveiled at Apple’s big announcement event tomorrow, but let’s not forget that we’re expecting a couple of new iPads as well, the most notable of which is the long-rumored iPad Pro, which is supposed to Apple’s biggest tablet to date. We won’t hear anything official on the device until tomorrow, but for those of you who lack that kind of patience, 9to5Mac has released a fully detailed report on the 12.9-inch device ahead of the event.

Alongside the new iPhones, new Apple TV, new Apple Watch bands, and a gold anodized version of the Apple Watch Sport, Apple plans to debut a pair of new iPads on Wednesday: the larger iPad Pro and a new iPad mini. Since our report last week that the iPad Pro would be unveiled at this event, we’ve gathered a few more details about the device from several sources who have either used the iPad Pro or are familiar with the product. Unlike earlier iPads, which have started at 16GB of capacity and been designed to appeal in both pricing and size to the masses, even the base model iPad Pro will have features fitting its name. We’re also hearing that it’s coming a little later than originally expected, but will still make it out by year’s end… First, we understand that production of the new tablet is running slightly behind schedule. While Apple still plans to announce the device this week, open up pre-orders in October, and begin shipping in November, we understand that the first shipments may fall towards the end of November. Even then, it seems likely that the device will experience initial supply constraints, despite a higher set of price tags than existing iPad models.
