Website of the original source has been hacked by 4chan/Anonymous in retaliation.
The report sources a man named Brad, who says he worked as a Rockstar Games marketing manager, before starting a marketing firm of his own.
The website for Brad's firm, called Rantic, has since been hacked by Anonymous and 4chan, with the message "Hacked by 4chan, Give us our GTA 5 for PC," left on the homepage.
In the same report, Rantic Chairman John Hoffberger says that "Rockstar never wanted to release a PC version of GTA V, but due to high public demand, they were forced to do so."
While the FoxWeekly report says the next-gen (PS4, Xbox One) Grand Theft Auto V release dates should not be impacted by the PC version turmoil, other reports now suggest that next-gen releases could be pushed into 2015.
VG247 says Rockstar brought next-gen versions of Grand Theft Auto V to Gamescom earlier this month, but those versions were only being shown to retail partners. The "chatter" also pointed to a delayed release, with no new versions hitting until 2015.
The Grand Theft Auto V E3 next-gen reveal pointed to a Fall 2014 release on the PC, Xbox One, and PlayStation 4.
We have reached out to Rockstar for comment on the PC cancellation, as well as the console delays. We'll be sure to update accordingly once new details come to light.
Minor Update: Assuming the Rantic website is restored to working order soon, here is a screencap we took of the hacked homepage.
