In addition to some new TECHNIC parts expected in 2H sets, want which we've been already discussing *,
there are some new ones, appearing now with the new Space Police and Agents sets. Despite being highly specialized, they may turn to be useful.
You may found them on sets 8967, 5970, 5971 and 5972.
*) We also suspect about a new part design for TECHNIC gear racks [2, 3], which however we have not yet seen any images from that part alone.
