Sony is preparing for the "slimmest" launch in PlayStation history, inviting press to a breakfast briefing next week. The invitation simply teases what is coming, with it stating: "Following the biggest launch in PlayStation history, join us for an introduction to the slimmest".
We could see two things: the PS Vita Slim - which is what it will most likely arrive as, or a complete surprise: the PlayStation 4 Slim model. The former will be unveiled, but the latter would be an interesting device - especially this close into the PS4s lifecycle. The slimmer PS Vita Slim would be 20% thinner than the original, and 15% lighter.
