I have never played a J&D, but have played Daxter on the PSP and loved it. Uncharted was different class though.
Going by rumours, I think we are more likely to see Uncharted 2, but Ready @ Dawn could very well be involved in a J&D game for the PS3...who knows though.
But being honest, I doubt ND could pull out a game every 12 months for the PS3, who knows, maybe they could, but I would be very surprised if they could churn out an Uncharted sequel in 12 months. I would expect the game to appear next year.
Prediction (June 12th 2017)
Permanent pricedrop for both PS4 Slim and PS4 Pro in October.
PS4 Slim $249 (October 2017)
