However, this is likely to change this year, as both Sony and Microsoft have vowed to release the Xbox 720 and the Playstation 4 this year.
The Xbox 720 is rumoured to only function when a Kinect (or a Xbox 720 equivalent) is plugged in. Rumours also indicate that this will be sold with the base system, possibly increasing the price of the floor model.
Similarly to multitasking capabilities of other devices, the new Xbox 720 may allow you to run several games and apps simultaneously, allowing the player to quickly switch between applications.
