Sandro Magister discusses happenings in the curia on his site, www.chiesa.com. He writes mainly on religion and Catholicism - in particular on Vatican happenings, in the Italian weekly, "L'espresso". He has some very interesting articles on his website and I frequent it a few times monthly. It is not updated often.
I also heard Joan Lewis talking on EWTN Radio that speculation is pretty high that something will be happening the first week or so of June. She's got some nice coverage of Pope Benedict's papal visit to Poland at her EWTN blog too.
