Yesterday, Sony filed a trademark for Rise of the Kasai in Europe.
This is not surprising. Last December, the company already released Mark of Kri (PS2) on PS4 via the ‘PS2 Games on PS4‘ selection, so it was just a question of time that its sequel, Rise of the Kasai (also originally released on the PS2), came to PS4.
Furthermore, Rise of the Kasai PSN Trophies have also been discovered. An official announcement should be imminent.
