They'll do it will closed circuit TVs. People will go to Assm Halls and watch televised talks. At least for the "keynote" talks where they will "pipe in" from the conventions where GB or Bethel brass are speaking.

Ugh...that would be torture. Total snooze-fest.
Anywhooo, whatever they have up their sleeve, we'll probably have to wait until January 2013 for official word. (Isn't that when "the letter" usually gets sent out? Commence the stampede to the Information Board T M so you can book the best place of the Required Recommended Lodging TM List!)
As an aside, I noticed the 2012 DC program posted on JW.org is printed in the oh-so-creative color of black. Is it actually printed in BLACK this year? And the badge cards? (I have yet to "forget" to pick mine up.) I'd laugh if it is...maybe black represents the death of the 3-day DC???
