It appears that a sequel to PlayStation 4 launch title Knack is in development.
That's according to a – now deleted entry – on the LinkedIn page of an employee of Taiwanese development company, XPEC Entertainment. Thanks to NeoGAF for spotting this.
The developer's LinkedIn said that they have been working on ‘animated 3D characters motions and cutscenes of PS4 system' for Knack 2. This project started in May 2015.
In addition, they had worked on the PlayStation 4 version of the long-in-development Final Fantasy XV.
Platformer Knack's development was led by Mark Cerny, the man who developed the architecture of the PS4. It was part of the console's launch line-up, which also included Killzone: Shadow Fall.
