I just heard they are going to be releasing a trailer for GTA V on Nov 2, 2011. I played all the GTA games (except GTA 2) and am looking forward to that game, but I am a little surprised they haven't released GTA IV: Vice City. If they had released a few new GTA IV game with different locations, I would have really appreciated it, as the basic gameplay doesn't need to change (though some of the frustrating missions should have been fixed). Vice City is my favorite game of the series.
So my question is, if they are calling it GTA V, does that mean there is a new game engine? I would think it's a bit deceitful to call it GTA V if they are using the same old engine.
Anyhow, I will have to wait 6 months after its release to play it, until the release it for PC.
