The only reason I can see them dropping the 4dr M3 is to force people into the M5. No thanks. Giving us the M3 GT as the replacement is some kind of sick joke.
The M5 is the only car they don't screw with yet with the M3 it's the wishy washy "we'll do a 4dr and then we wont". The competitors don't mess about with their formula (RS4/5/6, C63/SL) but BMW does. Why? I'll keep buying 4dr M3s as long as you make them, maybe even with FI if you get your HPFP and DI issues sorted out, but otherwise it's just distressing hearing the 4dr dropped.
