Rockstar has not officially detailed a "GTA Online 2." An online mode in the spirit of GTA Online is widely expected, but its name, launch timing, and whether progress/purchases carry over are not confirmed.
What's actually known
- [Reported] An online component is expected — Rockstar's recurring-revenue model effectively depends on it.
- [Reported] Industry expectation is that online launches after the single-player release, not day one.
- [Rumor] "GTA Online 2", lobby sizes, and any GTA Online → GTA 6 carryover are speculation, not Rockstar statements.
Bottom line
Expect online; don't expect details or a day-one launch yet. We'll track every official word here and in everything we know. For the single-player timeline, see the release date.
