GTA VI Platinum Trophy

So I was just thinking how long do you guys expect for a full completionist run where we get the platinum trophy for the game, this is usually a huge task for Rockstar Games and not everyone is strong enough to take on it Do you guys think the platinum will be harder than RDR2 or much more accessible. Also it is very likely that online trophies will be included but Online won’t launch Day 1 so is it likely no one can get platinum for a while then?
