There's just something special about an Xbox pad. The feel, the look, those clicky buttons. We at PC Gamer like it a lot, and it's been reported that three new prototypes are being worked on, so it seems like there's going to be a lot of choice in the future. The next generation of Xbox controller also reportedly has cloud gaming at the heart of its very design, though I really hope it gets some quality of life improvements like Hall effect sticks.
In the Xbox-focused podcast, Xbox Two (via Notebook Check), Windows Central's Jez Corden revealed that there are "currently three Xbox controller prototypes" in the works. Corden has been reporting on everything Xbox for some time, and is generally well regarded when it comes to insider Microsoft information.
