As Rockstar Games remains mum about the release of Grand Theft Auto for different platforms, the game continues to appear on international retailing websites.

The latest website to boast an unannounced version of Grand Theft Auto V is SimplyCDKeys. Recently, the website added a listing for Grand Theft Auto 5 (GTA 5) Steam CD Key.

"Please Note: You will need 8GB of storage space on your hard drive in order to install and play Grand Theft Auto V," the listing's description reads.

The Steam CD key is available for pre-order for £44.99. To make matters even more suspenseful, the website goes as far as to list its own release date: Sept. 19, 2014.

In addition, GK4.me, a German website, is selling Steam keys for a PC version of Grand Theft Auto V, but is simultaneously raising red flags for some gamers.

"The worrying thing is that when demands are high, the scammers will tend to take advantage of these situations," Motoring Crunch reports.

For the past few weeks, PC gamers have found hope in Amazon, whose Germany store has a listing for Grand Theft Auto V PC, and whose French site used to have the same. Amazon Germany lists Grand Theft Auto V PC at 60 euros and says it is compatible with Windows 7 and Windows Vista but does not list minimum system requirements.

Additional sources claim that Rockstar Games will soon release Grand Theft Auto V on next-gen consoles as well.

At Sony Computer Entertainment's Destination PlayStation event in Scottsdale, the future of the console was discussed, and according to Lokiolr, a Twitter user who describes himself as "Co-founder of the Voice Of Geeks Network Host of Orange Lounge Radio XBOX," Rockstar Games' presence was minimal but promising.

"Rockstar had something amazing to show but bailed at the last minute. Expect an E3 announcement from them this year. Likely GTA V on nextgen," Lokiolr said via DualShockers.

Eurogamer Portugal reports that Worten is now accepting pre-orders for Grand Theft Auto V for PS4 and is even "accepting cash," according to Segment Next.

"We would inform you that we have the information that Worten stores will sell the game in question," Worten said according to a Google translation via Segment Next.

 In addition, Czech retailer SuperGamer has listings for the game for PC, PS4 and Xbox One. It claims the games will be available starting June 13. Fans say the rumor has at least some credibility as the date is a Friday, a popular day for developers to release games.
