JKR does say that the Dursley's will play a bigger role in book seven.
And some careful readers have noted that Dumbledore gave all three
Dursleys the address of Grimmauld Place, twice.

It seems a reasonable guess Petunia will move her family to Grimmauld
Place for protection from whatever she is afraid of. And this will
chase Harry back to Hogwarts.

I'm sure you are right - Dudders is going to suffer some unpleasantness.
