Pretty sure it is, that's the main difference with the team roster. Nightwing gets his New52 suit, but the team made in JL vs TT is in tact with Damian, Starfire, Raven, Beast Boy, Blue Beetle, and Nightwing. Terra was teased at the end after the credits on her way to Titans Tower in JL vs TT. 

Jericho looks like he's being introduced, Brother Blood is coming along as a member and/or leader of HIVE, and Deathstroke still looks as he does in Son of Batman. I hate that Damian took his eye in this universe, but it should set up some interesting drama in Judas Contract.
