Release of new NXT Tour, NXT Tour S, Velocity and DT Solo announced today.  I played a prototype black marked ball last Fall.  I think it's a NXT, but not sure.  Can someone confirm?

If you got black, my guess it was NXT Tour S

I, too loved the test balls I tried back in October and would love to purchase them... just don't know which one it was!  The optic yellow was a unique color so I am hoping I can tell the difference in the just announced NXT line and the DT Solos yellow balls.
