That is what I read here at the page of the new channel changes that are coming from Time Warner Cable: http://www.timewarnercable.com/nynj/learn/cable/channelchanges.html
Those of you with Verizon, Cablevision or OTA may have to check to see if you're getting Univision in HD even earlier than that.
On or about December 7, 2009, in Manhattan and Brooklyn and Queens we will launch WXTV (Univision) HD on ch. 741 and WFUT (Telefutura) HD on ch. 768. On that date in Mount Vernon we will launch WXTV (Univision) HD on ch. 716 and WFUT (Telefutura) HD on ch. 768.
