The Census Bureau will be releasing the update to the 2010 Census Summary File 1 that will include characteristics for urbanized areas on Thursday.   Here’s the announcement from the recent Tip Sheet:

Summary File 1 Urban/Rural Update File — Adds urban and rural population and housing unit counts to the 2010 Census Summary File 1 released in 2011. The update provides detailed tables on age, sex, households, families, relationship to householder, housing units, detailed race and Hispanic origin groups and group quarters population for each of the nation's urbanized areas and urban clusters, and for the urban and rural portions of the United States, states, counties and places. (Scheduled for release Sept. 27.)

Also for an update on the social and economic characteristics, in a conversation with ACS staff, I was told that the ACS data files will not include the new UA until the release of the 2012 ACS in Oct-Dec of 2013.   We are not getting them in the 2011 ACS because ACS staff did not get the geographic boundary information in time.
