Yes, but you must remember Pakistan had to wait for the enemy to make up their decision in regards to what new platform they were going to induct. After the failure of the MRCA tender, they eventually selected off-the-shelf Rafale.
Had India dragged on the MRCA tender further, Pakistan would had been happy producing even more Block-2s, around 12 a year.
New Blocks will only be built If the enemy acquires some state of the art technology that isn't already present with the PAF. PAC is not going to willy-nilly produce new blocks just for the sake of it.
