Two projects a reliable source informed me of a long time ago, but we are yet to see any updates or confirmation of. Rockstar Editor and a next-gen version of RDR2.   I believe the last update regarding the Editor was from @VideoTech who found a leftover of the Director Mode within the Naturalist update preventing Jack model from being used.   Seeing GTAV next-gen version, we should just expect a Performance/Fidelity mode, increased FPS and maybe ray tracing for RDR2 next-gen
