Wagner's Ring Cycle on SACD from Adelaide, Austral

I read that update on SA-CD.net some time ago and wondered how long it will be, before these become available. I have been disappointed thusfar with the number of Operas becoming available on SACD, so I'm quite anxious for this one.
btw... if you like opera, I HIGHLY recommend Falstaff by Verdi which was just released on the LSO Live label. It's fantastic.
