That´s great news, I always thought it would be pretty odd to have an M4 instead of an M3 even if it was the same thing. I also thought it would be better to keep the inline 6 instead of a new V8, and although I still think that way it won´t be so terrible since it appears to be a super happy revving V8 that weights no more than the current M3´s engine
I just hope they keep it that way.
