One of the cons about the next gen technology is games take longer to develop as little details can be enhanced a lot more than before.
I know. It just comes to a point where the wait is too long and you're a different person with different tastes by the time it finally comes out.
I mean if 2025 is the actual release date we're talking about a 12 year gap.
2013 - GTA 5
2013 - Grand Theft Auto Online
2025 - GTA 6
I know the 'quality' isn't as good but look at the same 12 year gap from GTA 3
2001 - GTA 3
2002 - GTA Vice City
2004 - GTA San Andreas
2004 - GTA Advance
2005 - Liberty City Stories
2006 - Vice City Stories
2008 - GTA 4
2009 - Two major single player DLCs for GTA 4
2009 - GTA Chinatown Wars
Then you have all the mobile ports for GTA 3, GTA Vice City and most of the games above ported as well.
I'm surprised we haven't seen GTA 4 on mobile yet to be honest.
