While Apple typically uses the iPhone to introduce new design language, last year's iPad Pro may be taking the lead this time around. Kuo, whose predictions are typically accurate to a degree, describes 2020's reworked design as a segmented metal frame sandwiched between two layers of glass or sapphire. That sounds pretty similar to current iPhones, but Kuo believes the "metal frame surface will be changed to a similar design to the iPhone 4," as opposed to the X's rounded frame.

Unifying the designs across iPhones and iPads seems like an obvious step, but Apple usually doesn't change much for its "S" refreshes. The new design may indicate that Apple will simply skip the iPhone 11S and go straight for the iPhone 12 like it did when transitioning from the iPhone 7 to the 8.

The new look will be a selling point for customers, but Kuo warns that production prices will likely rise thanks to the reworked frame. Apple has faced more backlash than usual for its high prices, but seemingly has tried to curb complaints with the iPhone 11's $699 base price. Raising prices again won't be well received, so hopefully Apple absorbs most of those increased costs.

The iPhone X's silhouette was stunning at the time, but after several years, every design gets old. Whether the next iPhone borrows from the iPad Pro or goes in a completely different direction, it will be sure to create buzz. Hopefully Apple figures out how to get rid of that notch, though.
