The VooFoo Studios PS3/PSN game Hustle Kings was used as a starting point for the upcoming NGP version of the same name. This version is pool on-the-go, on a shiny OLED screen, with touchscreen controls that let you line up and take shots and choose options.
There's plenty of online functionality in the portable version of Hustle Kings. In this one you'll be able to get your asynchronous gameplay on, with push notifications that will tell your opponent that it is his turn. There's also synchronous gameplay and cross platform support, meaning that you'll be able to use your NGP to play against someone on the PS3.
There's no release date for Hustle Kings yet, but we do have some new screenshots!
