It's more or less the same, hype should be for people who don't have consoles and have yet to play this game. Previous GTA releases on PC were great because it looked so shitty on PS2 that you lookd foward to bumping up the resolution alone. Playing GTA3 on PC when it first came out on 1280x1024 was amazing, same for vice, and same for SA, especially when they gave us anti aliasing.
This would just be like 'oh', infact I think it looks worse. Console screens looked more gritty, this looks kinda 'smooth' and dated in some SS. Ah well, maybe all them shitty car mods that were too high polygon for the last gen of GTA games will finally find a home in GTA4's graphics engine
