not necessarily to be honest i see nothing that the ps3 and 360 aren't capable of there seems to be no anti anti analyzing, the texture's aren't exactly ground breaking, there is obviously no particle effects that have been seen so far. its just doesn't seem as next gen as everyone is making it out to be.
plus there are some problems in the pictures themselves that they should worry about like that right front tire on the truck.
The game still looks great tho, it just didn't astonish me to the point of believing its next gen.
The textures though stand out. It would probably push the limits on the consoles.
As far as rumors go though with a map being EXTREMELY LARGE I think it would be possible on PS3 and Wii U because of the 25 GB disks could handle it all on one. I HATE IT when the areas have to be done on separate disks like LA Noire and I think Rockstar said. That they hate doing that too.
