I'll be waiting to buy this one a few weeks or more after release on the PC... GTA IV was a turd, badly ported and lacking in almost every area.
If they can make this one as good as GTA SA... I'm in, visuals are nothing if the gameplay is lacking. SA had so much more to offer than IV.
I'm alsos till sore that I built a new system in preparation for GTA IV and it ran like a bag of sand on a high end system in 2008... because as Rockstar claimed... it was made for hardware that didn't exist yet... I think that's a f*cked up statement worthy of the late Steve Jobs.
It was only 2yrs later in Nov 2010 when I built another new system, that I found I could play the game with an acceptable frame rate of 40fps... but still couldn't turn everything to max, even with 2 video cards in Xfire mode and 2GB of vram. and a quad core CPU running at close to 4GHZ and 8GB ram.
If they make that kind of screw up again... I won't be buying it.
