If the nose has changed, it suggest the floor is very different as well.
Agreed. I am not surprised by a nose change for a couple of reasons
Changes to the floor edge and diffuser throat dictated by regulation change might cause a certain floor philosophy to work better forcing them towards a different nose/fw design than previously
And the fact that RB seemed to change floor concept fairly substantially midway through the rb18's life cycle (ditching the double outboard fences at the French GP) without making any changes to the nose/fw to accommodate that. It makes sense that the rb18's nose/fw was designed to work best with the car's original floor, and any departure from that floor design (which they already have decided to do) might be optimized with a nose/fw change
