Take it with a pinch of salt, but some guy named MS Nerd claims Microsoft plans to release a $100 Xbox Lite variant in late 2013. According to the source, this new gaming console will be based on the ARM platform, which suggests it will be aimed at casual gaming.
The Xbox Lite will be an ARM-based platform that should receive a price tag similar to that of the Apple TV, so around about £100 in the UK and $100 US.
In fact, it sounds a lot like the Xbox Loop, a product code-name previously outed by the same guy in November and described as smaller, cheaper and Kinect-focused product.
After that will come the 'Xbox Next', says MS Nerd, which we prefer to think of as the Xbox 720 (although it's very unlikely that we'll know the new Xbox by that name when it launches).
