The 1 Series successor of the current F20 is the F40 which we know is moving to a FWD configuration. The 2 Series successor to the current F22, is the F42, which will retain the RWD configuration. This means you can expect the M240i and M2 to stay RWD as well. The F43 convertible has been cancelled, so anyone wanting an open roof will need to look at the Z4 Roadster or go up to the 4 Series, both of which will be moving to a fabric roof.
The 2 Series Gran Coupe F44 is reported to also be FWD, along with the Active and Gran Tourer variants of the 1 and 2 Series.
