Yes. I expect a USCCB announcement to soften the blow shortly. How they are going to enforce a rule, if you will, that they have been flaunting for decades is beyond me.

Wouldn't surprise me in the least. The national bishops' conferences are going to be one of BXVI's most difficult challenges because they are bound and determined to maintain the status quo. It's been just fine for them, thank you - they get to swan off to pointless meetings in comfy hotels, have the press fawn over them for their liberal positions, and - well, further speculation might be uncharitable.
These organizations have no canonical status in Church governance, but they are a real obstacle to any attempt to exert authority from Rome.
