Wednesday's launch could see some of the latest iPhone features like Face ID brought to some of its lower-end models. That could drive up the price of iPhones in general but may make the cheaper versions more appealing to cost-conscious Asian consumers, said IDC's Kaur.
Apple may also choose to knock down prices of its older models once the new line comes out.
"For consumers who want to be in the Apple ecosystem but do not want to spend that kind of money, it's a good alternative," Kaur said.
Whatever it does, Apple needs to find a way to sell more in Asia.
"To ignore these markets would not be the wisest decision," Kaur added.
