Rockstar is really >not< as big of a game publisher as many people think it is, at least relative to the bigger names out there. Also unlike Ubisoft and EA, Rockstar is particularly known for 'perfecting' its games by focusing their entire workforce on one title before it is released. In other words, there's no way GTA 6 can be designed and released in such a short time after RDR2.
2021-2022 is more realistic for GTA 6. Especially since GTA 5 is still profitable for Rockstar.
Since the VR version of L.A. Noire was only released 6 months ago, I would bet L.A. Noire 2 is more likely before GTA 6.
