While we're getting new-gen versions of GTAV (at some point), the visuals may not be the only thing being upgraded when the game re-releases.
Cara Delevinge, who was the voice for Non Stop Pop FM in GTAV, has tweeted that she's returned to Rockstar to update her radio station ahead of the game's new-gen releases.
If true, it's a great touch and shows Rockstar going the extra mile to update the game beyond a visual overhaul. We've contacted the company to get a confirm on the update, and whether we'd expect to see the same work go in the other radio stations.
