8. Zero pop-up and slowdown
Even though the visuals in GTA 5 will probably blow everything else away, we just hope that Rockstar finally manages to eliminate pop-up and slowdown. The GTA series has been plagued by these graphical issues since it moved from 2D to 3D and by the time the next round of consoles are on the market we hope they'll be a thing of the past. In GTA 4 it's hard to look past these issues when they are at their most severe, and it'd be a shame to have to suffer the same problems for yet another generation of GTAs.
