In a press release from Tim Frank, VP of Basketball Communications, he wrote, "The NBA is continuing to make progress with the Players Association toward finalizing the CBA and both sides are optimistic that the agreement will be signed by the end of the week.  

"Once the agreement is completed, the league and the union will take 48-72 hours to educate teams and players as to the details of the agreement, after which player signings will begin."

This should make the new end to the moratorium sometime after the first of August.
