No radical design alterations are likely to be made for the M4 iMac. The main change will be the presence of the M4 chip, which is expected to have enough horsepower for an 8-core CPU and an 8-core GPU though this is still ambiguous. One other important advancement is that the RAM will be increased to 16 GB, which will enhance multitasking and performance. Other than the new chip, only a Magic Mouse and a Magic Keyboard with a USB-C port are expected.
