EA Origin producer 'Redditor Offspring' has dismissed the requirements saying DICE is yet to finalise them. A tell-tale sign these aren't genuine is the lack of Windows 8.
Even the alpha system requirements for Battlefield 4 mentioned the new Windows OS, which wasn't supported at the time. Ubisoft appears to have removed the posting.
"I don’t believe the final system requirements have been decided yet, and this looks a lot like placeholder system requirements from BF3 with a couple of tweaks," said EA employee 'Redditor Offspring'. "I know everyone’s excited for BF4 news, but I wouldn’t trust an Ubisoft page with system requirements for it just yet.”
