In early September, Apple usually holds an iPhone event every year, so we can expect iPhone 13 to be revealed around that time. The iPhone event was postponed to October 13, however, as 2020 was an particularly challenging year for everyone. In the Apple supply chain, COVID-19 caused a lot of disruption, which ultimately postponed the launch of the iPhone 12 and its stablemates until October 2020. (Two of the models will not actually go on sale until November, in fact.) But assuming things return to a semblance of normality in 2021, with a September update, the iPhone 13 could return to its traditional position in the calendar.
How much is this iPhone 13 going to cost?
The iPhone 13 series, which is priced as follows, will cost almost as much as the iPhone 12 series:
iPhone 12 mini - $699
iPhone 12 - $799
iPhone 12 Pro - $999
iPhone 12 Pro Max - $1099
iPhone 13 display
In terms of display sizes, we should assume that the iPhone 13 series will have phones with display sizes similar to what the iPhone 12 series has, if not slightly bigger, according to early iPhone 13 reports. This implies that we'll theoretically get the following:
iPhone 13 mini - 5.4-inch display at a resolution of 1080 x 2340 pixels (476 PPI)
iPhone 13 - 6.1-inch display at a resolution of 1170 x 2532 pixels (460 PPI)
iPhone 13 Pro - 6.1-inch display at a resolution of 1170 x 2532 pixels (460 PPI)
iPhone 13 Pro Max - 6.7-inch display at a resolution of 1284 x 2778 pixels (458 PPI)
The iPhone 13 series are likely going to sport flexible OLED displays, instead of LCD. There are also expectations for the iPhone 13's displays to have a 120Hz refresh rate,

The camera module on iPhone 13 is not expected to differ significantly from the module used on iPhone 12 and iPhone 11.
