Normal law is a misnomer on an Airbus.

It's actually quite a complex blend of multiple different flight control algorithms which vary depending on phase of flight and speed (ie, Airbus will tell you that sidestick demands load factor in flight, but that's only true at high speeds. Below that it's actually direct elevator deflection with a load factor feedback loop, and below that it's AoA directly).

​​​​​​​Can't tell you any more about the new rotation law as I now fly the Airbus wannabe, also known as the 787, and no longer have access to the neo FCOM.
