I think TechEd 2005 is shaping up to be awesome again this year. They just posted the list of sessions (well, most of the sessions anyway). I can't link directly to the architecture sessions, but you can filter the list to show just one track at a time if you want to. We haven't got speakers or abstracts posted yet, but I can tell you that we've got some good speakers lined up like Scott, Ted, Roger, Rocky, and Steve.
Of the ARC track sessions, I think I'm most looking forward to "Building and Using a Software Factory". I jokingly call this session "Here's the Beef, Chris Sells". Chris blogged that he wanted a concrete example of a software factory. It turns out that we've been working on a concrete example since before OOPSLA. In the TechEd session, we'll see how far Michael, Jack and Keith have gotten since October.
