Hello There! Welcome to the World of Pokemon, my name is David. Pokemon Go, is the interaction between Pokemon, and the real world. Allowing you to find random pokemon in the world, and capture them. Just like your favorite video game.
A small device called a Pokémon GO Plus will enable Pokémon GO players to enjoy the game even when they’re not looking at their smartphone. The device connects to the smartphone via Bluetooth and notifies the player about events in the game—such as the appearance of a Pokémon nearby—using an LED and vibration. In addition, players can catch Pokémon or perform other simple actions by pressing the button on the device. Pokémon GO Plus is being developed and manufactured by Nintendo Co., Ltd.
Now this Pokemon Go will work in conjunction with most smartphones, and will be coming out with some sort of PokeWatch(PokeGear?!?!?!) Which will hold all the functions on the application.
Pokemon Go Launches in 2016.
