Here's a link to an update from Michael Weiss's official website. His schedule for the 2004-2005 season includes appearances with three NBC-television specials, with skating accompanied by live vocal performances by Andrea Bocelli, Kenny Loggins, and Michael McDonald.
There was no mention of the recent US Nationals on the website. It appeared that the news section had not been updated since Nationals. Weiss, of course, is identified as being a three-time US chamipion, two-time World bronze medalist, and three-time Olympic team member.
