Is GTA 6 Online going to be a standalone game this time?

Hey guys, I’ve been thinking about something. If you check out the GTA 6 page on the PlayStation Store, it literally says "1 player" and "Offline." Meanwhile, the GTA 5 page clearly states it's multiplayer and has an online mode. This got me thinking - and I wanted to call it first before anyone else talks about it - could GTA Online be dropping as a completely separate standalone game? It honestly makes sense, especially considering Rockstar did the exact same thing with Red Dead Online after a while. What do you guys think? Am I cooking or am I just overthinking this?
