Rockstar extended the GTA 5 map for more than a decade through GTA Online, adding new heists, new districts, new properties and new interior systems. GTA 6 Online will almost assuredly continue that trend. This page breaks it down: given the blueprint of GTA Online, how is GTA 6's map likely to expand post-launch?

The GTA Online precedent
When GTA Online released in 2013, it started with essentially the GTA 5 map untouched. Over the next 10 years, Rockstar added: Cayo Perico (a whole new island), Casino content (a huge new building/interior cluster), the Diamond Casino & Resort, the Music Locker, the Agency, the Acid Lab, dozens of new purchasable properties, and dozens of new businesses that you can own, complete with unique interiors. By the 10-year mark, the map was significantly larger than at launch.
Apply that metric to GTA 6: anticipate a similar 10-year cycle of additions, perhaps accelerated thanks to Rockstar's larger workforce and the denser baseline of the next-gen map.
Likely first-year additions
Year 1 GTA Online additions tend to be structured around introducing heists and profitable businesses. Expect to see both in GTA 6. Based on geography alone, here are some we'd expect: a casino somewhere in the Florida Keys (the Vegas analogue resides in another state, but a beach casino would fit the Vice City vibe perfectly), a port heist utilising the maritime district, a drug-running op set in the Everglades in the wetlands.
They don't add new geography so much as unlock existing geography. The map gets denser rather than bigger.
Year 2-3: new geographic content
GTA Online's Cayo Perico didn't show up until approximately year 7. GTA 6 Online could move faster on adding completely new areas - Rockstar has already telegraphed they plan on aggressively supporting GTA 6 Online. Likely areas to see first: an offshore island reachable through a mission, an inland city expansion (the secondary cities seen in trailer footage have lots of room for expansion), or a Cuba/Caribbean-analogue island.
Pure-online zones tend to be small but dense. Forget whole new states - think single-purpose sites loaded with interior content.
What probably won't happen
Rockstar rarely replaces geography - they add to it. So no, Vice City will not shrink to make way for new neighbourhoods; new neighbourhoods will be added or current ones expanded/redeveloped around the outskirts.
Seeing GTA 5's Los Santos in GTA 6 Online as official content from Rockstar probably won't happen, because it goes against their approach of keeping fictional worlds separate. Modders will absolutely create it, though; keep an eye on GTA 6 map downloads for when that content becomes available.
How to track what's coming
Rockstar often telegraphs DLC months ahead of time through datamines, marketing teases, and in-game event hints. Fans datamining GTA Online have historically uncovered content months before it was even announced. They'll probably do the same thing with GTA 6.
