Not the last Ratchet and Clank
IG has not released any information saying that they are or aren't making another R&C, just because they are making I-8 doesn't mean anything, they even said that the Ratchet universe is huge, and that they will come back to it, if they leave it, yet I still read things like "this was the last R&C"
*OFFICIAL ULTIMATE R&C AND FF FREAK!*
