JW:

JKR has announced two things of relevance here:

First, that there IS an important revelation in DH about Petunia.  I do
not recall the exact words, but IIRC, she said that it WILL explain
DD's multiple correspondences with Petunia, and what Pet was able to
extract from DD in return for taking HP.

Second, JKR has announced that Pet is NOT a witch, not the squib who
JKR says will first perform magic relatively late in life, but instead
is a normal, unexciting MUGGLE who will NEVER perform magic, thank you
very much (to paraphrase the first paragraph in SS/PS).

However, Shelley, is it possible to de-power a wizard into muggleness?
Perhaps Dudley, not Petunia, is the recipient of such a "favor."  Such
a circumstance would be a hidden message behind DD's reference (in HBP)
to the Dursley's abuse of Dudley...
