There is no news of cancellation of Pakistan's AH-1Zs either.I believe deal for T129 is still alive.
There is no evidence of cancelled yet and still ambiguity is there regarding Engine issue.
Wait for some valid and authenticated information from either Party source.
Discreteness in Pakistan's defence acquisitions are growing day by day, we only find out a system has arrived on 23rd March or through a foreign leak of satellite pictures.
