Naughty Dog explicitly expained that even though they know about jak 4 they have moved away from it and are focusing on a new IP for a new game. The possibility of a Last of Us 2 is not possible and the making of an uncharted 4 doesn't seem certain. Don't get me wrong Jak and daxter is awesome but my feeling is that it won't happen.
well im afraid that's not possible because jax and daxter are no longer a naughty dog's game!! something like that! as far as i know the lastest version of jax and daxter ( the lost frontier) isn't made by baughty dog but by some other company, and to be honest...it kinda sucks...some positive aspects on that game but we all know that only naughty dog can do a badass version of jax and daxter...its a shame tho...i just finished the last game of this amazing game and im disapointed! pls if it's possible pls do it naughty! i mean this legacy is gold we all know that! and we have so much things to explore and discover! we are like begin! would be awesome a new jak 4...think about it
