As shown in a tweet from Gary Sussman Thursday, pre-cast concrete sections are now being added to the lower bowl at Barclays Center, giving the bowl an arena look, with openings to the concourse now plainly visible. 

Interior walls should start going up in early June; the weathered steel panels in late July then roof sections in early September. Looking farther ahead, the first seats should arrive around Thanksgiving, and permanent power up and running a week later.  There's even a target date for the scoreboard installation: February 22, 2012. less than nine months away.
