He's at his residence in Buenos Aires, he was discharged last Wednesday evening. His doctor said to the press, when he denied the death news, that his condition is serious but stable and he was receiving medical treatment at home. The same was said by the hospital where he was being treated.
Basically, he's very sick and being treated at home (either because he did a round of treatments at the hospital and is continuing now at home or because he's terminal and is spending his last days with his family and friends in his home).
He was spotted attending a polo match in Buenos Aires on Sunday, according to Dutch (ao) papers.
As for Max: she's on a 5- day trip to China for the UN right now (24-28 Nov) to discuss micro finance etc. Can you see any other consort (well, bar Leti) actually hold her own over there for so long?
But... but...she must be home taking care of the children!!! such a bad mother

(here's me on a semi-formal business trip for Japan for 5 days with Lil'P and the Pomster at home. But I'm a degenerate mommy.Also, I had some interesting discussions on the Imperial family over dinner the last few days....)
