pretty sure rockstar can't drop a super expensive horse... RDR2 is what it is, a western with a fun online component... the fact that GTAV has sold 75M copies means that their main focus will still be GTAV, regardless what RDR2 does... the cheat money they've made on GTAO means that a game like RDR2 can succeed without being just like GTAO... hell, just seeing the hype alone from a company that brought you GTAO is enoguh to guarantee RDR2 success, regardless of what it is... so bring on bully 2, max payne 4, etc... they've made nearly $4B on just GTAV (not including shark cards)... no game they will ever make can match that...
they will never reach what GTAV did, but you can always use a few extra bucks to fund GTAVI ... so use this time to finally make those other games, and keep a group still dedicated to GTAO and the future of the series.. but i am at the point where i can't imagine that GTAV's success will drive everything they do from here on out... GTA is GTA, the most celebrated series in gaming history... you can't expect everything you make to do the same ... keep the phenomenon to GTA, but still give fans others things FFS...
