The new Xbox One S (right) was announced at E3 2016. It's an updated version of the original Xbox One (left).
The first big difference is size: The Xbox One S is 40 percent smaller than the original model.
In fact, the power adapter for the original Xbox One is almost a quarter of the size of the new Xbox One S (which, thankfully, has an internal power supply).
The One S will come with an updated Wireless Controller with Bluetooth and a new textured grip.
The new Xbox One S, available initially in white, also adds support for 4K Blu-Ray discs and streaming, with HDR support on compatible TVs.
Microsoft has added plenty of ventilation to keep the console running cool.
The launch edition of the Xbox One S with a 2TB hard drive is coming in August for $399, £349 or AU$549. Later, you'll be able to buy smaller capacity models starting as low as $299. You can preorder all 3 models now.
