The usual disclaimer applies here. Neither Rockstar nor Take-Two have said Grand Theft Auto V will be coming to the PC, but they have made quiet noises about wanting to do that. Maybe. Probably.
Given that the others made it to the PC, the smart money would be on a release some time after the console versions. If that doesn’t happen, uploading these E3 images to this PC site will end up having been a waste of time. Which would be a shame.
