Studio director Simon Bennett told Den of Geek at PAX East that the release date is scheduled for the end of the month.
"We are looking at July 22nd, which is my birthday," he said.
The London-based indie studio revealed in April that the former Vita exclusive was coming to other Sony systems, as well as PC, Mac and Linux.
It is still unclear whether the game will take advantage of PlayStation's Cross-Buy promotion, where purchasing the game on one device unlocks the download on others for free.
"We already have a first playable up and running on the PS4," Bennett said last month. "It's like our little OlliOlli grew up and got some balls. It really feels amazing on the Dualshock too."
CVG's OlliOlli review observed that "while a class act on Vita, OlliOlli feels like it was born for PS4".
The review added: "Only a share button can satisfy that compulsion to flaunt your harmonic mastery of its assault courses."
