Najwa here:
"Ok I have this vague memory that Aunt Petunia couldn't be the late bloomer, and
if so please remind me, because I just feel that she might be the one. Her or
Filch, and Filch wouldn't interest me as much as Aunt Petunia becoming a witch,
so I'm hoping that memory is wrong. Who better to become one, and JKR 
seems to be hiding something about Petunia anyway, and sort of laughs 
at the idea of Petunia being a squib, but said it was a good guess." 

BAW:
JKR has said that it will NOT be Aunt Petunia.  I'm plumping for Uncle 
Vernon, myself.  Can you imagine his reaction after?
