Everyone can see some noticeable things that have changed about the new Ratchet & Clank PS4 game as well as the new movie, which we can see from the trailers as well as gameplay. One thing that's changed that we can all see is Chairman Drek's eyes and voice. His eyes have changed, supposedly because they wanted to attract more kids so they wanted to make more of a childish look for him. His voice has changed too, for a more childish voice as well. Qwark is similar to his future series personality, but it appears that he is a good guy now, rather than a villain in the first game. Who knows? He could be a villain after all, but it doesn't seem as obvious as the first game when Ratchet and Clank were betrayed by Qwark on Umbris.
Ratchet still seems to be the furry lombax we know, with a small change in terms of personality. In the first game, Ratchet appeared to not care for a while about Drek and his plans, but now it appears as if Ratchet is eager to save the galaxy.
Clank just seems as his future series self. However he appears to change in his personality, too. He doesn't appear to be arguing with Ratchet as often such as in the original game they often argued about Drek and Qwark. We do have footage of robots that appear to be like Cronk, but no appearance of Zephyr yet.
