Sony has dated Ratchet & Clank Future for October 27 in the US. Other regions haven’t gotten release dates yet.
I was late jumping on the Ratchet & Clank bandwagon, not owning a single game in the Insomniac franchise until Ratchet & Clank Future: Tools of Destruction. It really is a top tier platforming series that any fan of the genre should not go without playing. I’ve recently gone back and started buying the entire series for relatively cheap prices. You can snag each game new for around $20 or under on Amazon, excluding Tools of Destruction, which will run you around $28 brand spankin new.
