For quite a while there have been numerous rumors that the iPhone 13 will be portless and will support only wireless charging. This might be generally true as the iPhone 13 will have a larger charging coil in comparison to the previous model. However, the major difference would be that the iPhone 13 would feature faster charging as well as reverse charging.
With a bigger coil, the iPhone 13 would be able to manage heat better and hence allow higher wattage.

According to the leaked image below, the camera setups would be similar to the previous model however the overall size of the phone would be bigger than the iPhone 12 lineup.
