Will there be another ratchet and clank after tools of destruction?

Yes, the game after "tools of destruction" is going to be called Ratchet and Clank future Quest for Booty. Then after that will be Ratchet and Clank future A crack in time

and then a game called Ratchet and Clank All 4 One and possibly after that Ratchet and Clank Weapons X. Hoped that helped!
