This column, originally published on Sept. 8, has been updated to mention a recent code leak indicating Apple's next flagship iPhone will be called the iPhone X, along with a KGI Securities report discussing iPhone X production constraints.

As much as Tim Cook has talked about stepping up Apple Inc.'s (AAPL) efforts to plug product leaks, the rumor mill has arguably provided us with even more useful info about the iPhone X than it did about the well-reported iPhone 7 prior to its launch. It has also signaled that Apple will be unveiling a 4G-capable Apple Watch and 4K-capable Apple TV set-top at its September 12th iPhone event.

But there are still a lot of important details that the rumor mill has at best partly fleshed out. Here are some of the ones to keep an eye on:

1. Exactly how Apple prices the new phones

The New York Times and Wall Street Journal have each reported Apple's next-gen flagship phone -- code found within leaked iOS 11 firmware indicates it will be called the iPhone X, with two cheaper models called the iPhone 8 and 8-Plus -- will feature a starting price around $1,000. But it isn't known whether Apple will continue its habit of supporting three storage tiers, with an extra $100 and $200, respectively, charged for iPhones at the higher-capacity tiers.

For the iPhone 7 and 7-Plus, those tiers are 32GB, 128GB and 256GB. Given its high starting price, it wouldn't be surprising to see Apple only sell 128GB and 256GB iPhone X models, or perhaps 256GB and 512GB models, if it's feeling generous. It's also possible that Apple could take a page from its Apple Watch strategy and provide status symbol-cravers a "limited edition" iPhone X featuring premium materials and a $1,500 or higher price.

For the iPhone 8 and 8-Plus, odds are that Apple will stick with or stay close to the $649 and $769 respective starting prices sported by their predecessors. But with the company able to upsell consumers on the iPhone X, it could make sense to switch to two storage tiers here as well.

2. What the iPhone X is bundled with

The iPhone X's expected steep pricing has fueled speculation that Apple will bundle something of value with them. This would be much like how Samsung is giving customers who pre-order its $900-plus Galaxy Note 8 a choice of either a Gear 360 camera or a "foundation kit" featuring a 128GB memory card and a wireless charging pad.

With the iPhone X and 8 both rumored to support wireless charging, a charging pad definitely sounds plausible. Other possibilities include a year or two of Apple Music or Apple's increasingly popular AirPods.
