First up, no mention of Ginny at all, which satisfies me in one respect - since I do not deem her to be worthy of notice - but compounds my frustration at Harry being married off to her.

JKR rectified this. Her every astronaut/superstar/president-cliche windmill is still turning.

if Harry was sincere about 'deactivating' the Elder Wand by dying a 'natural death', the very LAST THING he'd want to do would be an auror! That's the sort of logic that JKR just can't do, or denounce.

I think "logic" has definitely gone out the window. Have you seen the Leaky-Cauldron chat? o_o
