I think we will see more iterations of this case (like the current 5520P), due to the size being attractive to clients who have been wearing ROOs. While I am a huge fan of rose gold, in general, the white gold is the way to go, in this case. I could see PP releasing a steel version with annual calendar or weekly complication. Now, if PP would release it on a nice bracelet, it would wear bigger than the 42mm betrays and create a huge demand, since many clients want a bracelet.
