A message appearing at the end of the latest Ratchet & Clank game indicates it won't be the last instalment in the series.
Downloadable title Ratchet & Clank Future: Quest for Booty will be released via PSN on August 21st. According to IGN, on completing the game you see the message, "The adventure continues Fall 2009."
So does this mean another PSN game or a full-length disc-based effort? Sony isn't saying, and the "Fall" date could be for the US only. Still. More Ratchet!
