Don't know about M1. I am NOT even sure about the P1 and S1 formats so just let it go.
I have seen some specimen papers but I wasn't allowed to borrow them, so sorry can't get those for you people.
I recently talked to my friends who gave their P1 paper, they told me that nothing had changed. I'm 99.9% sure about it.
Fidato appeared for the paper, he can be more sure about it.
