Sony is holding a big PlayStation even in NYC next month, where it's expected to unveil two new PS4 systems. A redesign of the existing model, and the long-rumored PS4K/Neo/More Powerful PlayStation 4. The one that will potentially support 4K gaming. In the meantime though it turns out that the PS4 Slim is indeed a real thing, and has been leaked ahead of its official announcement. How? Well, they somehow have already been sold via the UK version of auction site Gumtree.
