I have a hunch that the next gen M2/3/4 will retain DCT. The S58 will have nowhere near the 700N-m of max torque. I also doubt that the next gen M3/4 will be getting AWD. So an evolution of the current DCT would still be a great match for the next gen M2/3/4.
IMO, the main reason BMW went with the 8AT on the M5 is for cost. They did not want to invest in the development of a longitudinal DCT with a higher torque rating and compatible with AWD when they had something available off the shelf with these capabilities in the ZF 8AT. Further, due to the car's heft and AWD, the advantages of a DCT might not be as prevalent on the M5. There are DCT that can handle higher torque (Chiron: 1180 lb-ft, Ferrari 488GTB: 561ft-lb, 911 Turbo-s: 553lb-ft just to name a few). So IMO, it is not the inability for the DCT concept to handle the M5's torque, but it is rather that no "off the shelf" option was available to fit the M5 application that drove the decision.
