Michelin not amused:

There's a reason for Michelin not being amused: The FIA has no interest in ditching Pirelli, who is willing to put their reputation on the line to follow F1's stupid demands.

If I recall correctly Pirelli say they will introduce the overall tyre diameter to 710mm for 18" wheels --- even though many other categories use 18" tyres with 650 or 680mm overall diameter that is more similar to the 660mm overall diameter of 13" F1 tyres.

I take it, this is to align with LMP1 tyre sizes which have a 710mm diameter also?

As 2019 starts I'm thinking more about this. The total amount of deflection on current F1 setups is not insignificant but as has been stated, it's primarily sidewall flex. How much change are we really going to see? LMP1 suspension seems to offer a similar amount of mechanical movement to current F1 but offers less sidewall deflection.
Will we see extra development in wheel designs since the metal part is going to make up a larger part of the unsprung and rotating weight?
