At least three Xbox One pre-orders have shipped two weeks early in the US, with recipients heading to social media to detail their very early experiences.
The Verge is reporting that Microsoft has been quick to shut down the information leak, going as far as to temporarily "ban" the consoles from accessing Xbox Live.
However, one of the recipients who goes by the Twitter name Moonlightswami posted a video of his Xbox One on YouTube, as well as screenshots from his Xbox One dashboard.
More pertinently for Australia, Moonlightswami revealed the file size of some of the games that will be available for download from Xbox Live.
The largest reported was 43GB for NBA 2K14, while Call of Duty: Ghosts clocks in at 39GB and Xbox One exclusive Forza is 31GB. The smallest file sized noted was FIFA at 8GB.
Microsoft has said that downloaded games will be playable during the download process, and Moonslightswami reported that games could be played when the download was over 50 per cent complete.
These files sizes may give pause to Aussies who were hoping to move away from physical media when it came to gaming, with 30GB and above representing a large chunk of many people's monthly download allowance.
It also suggests that the 500GB hard drive in the Xbox may not be as generous as expected. Heavy gamers who purchase games via download may find their hard drive filling quickly, requiring them to delete files, only to download them again later if they want to replay the title.
