For many people, a 5G iPhone is sort of the holy grail of smartphones. It's highly sought-after but inaccessible--almost mythical among die-hard Apple fans. As other manufacturers have released high-end versions of their flagship devices with 5G capabilities, Apple has waited.

And, while the iPhone 11 Pro is certainly the best iPhone the company has made, it still lacks the ultra-fast wireless technology that's expected to bring all kinds of changes to how we communicate, how we work, and how we access content on a daily basis.

But now a report from J.P. Morgan says that Apple is planning to introduce four new iPhone models next year featuring 5G. In the report, analysts predict that the devices will range from 5.4 inches to 6.7 inches, with two models featuring 6.1-inch displays. Demand for these devices is expected to be enormous, with DigiTimes reporting that Apple has notified suppliers it expects to sell 100 million iPhones next year.

To put that in context, if the average price of the new devices hovers around $1,000, that represents $100 billion of revenue for Apple next year. Currently, Apple sells several models at lower price points. However, it's likely the iPhone maker will follow a strategy similar to those of other manufacturers, whose 5G devices command a premium over other models.  

Selling that many devices would represent a 25 percent increase over the expectation that Apple will sell 80 million iPhone 11 series devices. And, for comparison, roughly 15 million 5G devices have been sold to date. Of course, sales of those devices are limited by the fact that 5G is only just now becoming available in many parts of the U.S.

But that won't be the case next year. By the time Apple is expected to introduce the next iPhone in the fall, demand will likely be huge. And 5G isn't even the only rumored feature that could make the iPhone 12 a massive hit.

Here are a few of the features that look like they will make their way into the next iPhone:

Refreshed-Retro Design

I'm not sure you can actually have refreshed-retro, but the design of next year's device is rumored to be a throwback to the more square edge form factor of the iPhone 5. This would be similar to the current iPad Pro design but on a smaller scale. Aside from the unavoidable bump on the back of the device, I have little to quibble with the current design, but I'm on board with a new (old) design for the iPhone 12.

In-Screen TouchID

FaceID is great, but there are still a lot of applications when I definitely miss TouchID. Obviously, Apple decided it had to go to make room for more screen and less chin, but now there are reports that the company is in talks to use an ultrasonic under-screen fingerprint sensor from Qualcomm in the next iPhone.

The other benefit of the switch is that you no longer need the additional sensors required for FaceID, eliminating the need for the large notch at the top of the iPhone X and 11 series models. This could also mean that all of the devices take advantage of OLED displays, instead of the lower-end model sporting a Liquid Retina LCD version.

New Display Sizes

The current iPhone 11 Pro Max has a 6.5-inch display. The J.P. Morgan report says it expects that to increase to 6.7 inches, though with the other rumored changes, that doesn't necessarily mean the device itself would have to increase by much. I've never personally cared for that large of a display, but I know that some of you are in favor of a "more is more" philosophy. 

At the other end, the same report says that the smallest model is expected to come in at 5.4 inches, which is almost a half-inch smaller than the iPhone 11 Pro. If that's true, it could mean that Apple plans to introduce a lower-cost model, in addition to upgrading its current line. Either way, it looks like Apple (and its fans) could have 100 million reasons to look forward to the next iPhone.
