iPad Pro screen
This is where things get way interesting. First, the Korea Times reported, citing Apple's "local first-tier display supplier," that the 12.9-inch iPad Pro will sport an almost-UHD resolution when it arrives in early 2014.
A later rumor, this time from China's Pad News, pointed to both 2K and 4K resolution iPad Pro models in the works. Per the story, Apple is prototyping a 2K model that would likely exceed that of the Kindle Fire HDX 8.9's 2560 x 1600 (339 pixels per inch) and blow away the iPad Air's 2048 x 1536 (264 ppi).
A 4K iPad Pro would likely come in around 4096 x 3072, beating the 4K TVs available today.
There have also been a number of rumors that suggest that the iPad Pro will come with a slightly smaller 12.2-inch screen, so don't get your hopes up too much for a 12.9-inch model.
iPad Pro processor
Again, this shouldn't be a major shocker. The iPad Pro will almost undoubtedly use a beefier version of Apple's 64-bit A7 chip, if not the new A8X processor or even a completely new A9 chip.
It will be interesting to see whether 64-bit processing has an effect on the iPad Pro's enterprise capabilities. But what will be even more important is Intel's response to such a product, given its long-standing relationship with Apple on the MacBook line, Daily Finance suggests.
New rumours have also emerged courtesy of Macotakara that suggest that Apple will be including a completely new processor; the A9.
We don't have much more information about the A9 processor at the moment, but if it does exist then it looks like it will be an upgrade from the A8X processor found in the iPad Air 2.
iPad Pro camera
Not much, if anything, has been said of the iPad Pro's shooter. Given that this tablet will be as large as (although lighter than) a number of laptops, we wouldn't be concerned too much with what kind of photos the tablet can take.
More important will be the iPad Pro's front-facing webcam. Will we see a higher resolution snapper on the front for quality video conferencing? Well, we sure hope so. A truly HD webcam would get heavy travelers more jazzed about an iPad than ever.
iPad Pro eye tracking
To put an even finer point on the importance of the iPad Pro's webcam, Apple would be remiss not to include eye tracking technology. The company has already seen startups like uMoove interested in providing the tech, and IBT's sources claim that this will be a key feature.
The iPhone 6 is expected to come with eye tracking. Now, all that's left is to implement them in a way that makes sense on an iPad Pro. Sharing with others what we're looking at on our own screens in conference calls immediately comes to mind.
