The distressed look of the Motiv logo is reminiscent of the Primal Rage and the new Rebel Tank (current lineup).
As far as retired balls, the Cruel line (4 balls), Tank, Primal series (3 balls), Recon series (2 balls) also had the same distressed logo.
That being said, a new entry into the Primal line would make a lot of sense based on the success behind the Primal Rage. Only thing that I wonder if if the ball will be the replacement for the Primal Rage or a new entry.
Also, Motiv's Facebook page also has Scott Newell throwing a dull dark green ball which doesn't match anything in the current or retired lineups. Will have to wait and see.
