i totaly agree on the everyone will buy it front, and i dont think people are getting trired of GTA, but I feel from looking through sites and what people are saying is that they need something new.
im one of the biggest GTA fanboys out there, lol.. i LOVE GTA, all im concerned about is that they try and push the system far too far and sometime it can get a bit over ambitious at times. (mind you.. pushing the PS3 to its limits, may take a while

)
i did love SA, it was a great game, but I loved Vice City more at the first time of playing SA.
recently ive been back to SA and ive got to say that i do 'now' feel that is its superior to VC.
but why didnt i think that at the time? a lot of people feel the same way as me... GTAIII was the greatest leap in gaming imo, was incredible..
I want that to happen again, new GTA, new console!! i just dont want them to mess it up, i want content over looks and brass.
i dont think im going to be dissapointed though, I really do have much faith in R*, i just love GTA so much that i would rather it leaped a lil in the right direction than a lot in the wrong.
