My thoughts have been that he is already out.
I think the US extracted him and flew him out of a UK airbase to Ramstein/Landstuhl.
Landstuhl med facility is secure. It's where the Benghazi injured were taken.
I was thinking Assange must have medical issues after 7 years and Ramstein is a good choice for treatment and convalesence.
Thinking he's out already and this article is setting up the 'cover story'.
