We touched on it yesterday in the hubbub of Sony Japan & Asia's press conference, but here's a proper look at the Metal Slime PS4 that's coming to Japan. We're guessing your two immediate questions upon discovering this are 1. Why? 2. What's that thing?
Well, the why is to commemorate the release of Dragon Quest Heroes, the new PS4 and PS3 Hyrule Warriors-like crossover that will combine the world of Square Enix's RPG series with action crafted by Dynasty Warriors devs. That's due in spring 2015. As for what that thing is - the happy little slimy dude - it's a removable USB cover rather than a permanent fixture. We're filing it under S for "Sure..." and Y for "Why not, I guess?"
