PSO2 will be released on 3 platforms, Windows PC, Vita, and Smartphones.

The details:
PC Version
The PC version is the main flagship platform for Phantasy Star Online 2, where everyone can enjoy playing it on even low end systems.
Vita Version
The Vita version is primarily for portable players, that shares the same data with the PC version, and can also play together with them at the same time. Unlike Playstation 2, Playstation Vita can support large scale system updates and system modifications. In addition, there are measures to prevent against cheating, because the character data is stored online.
Smartphone Version
The Smartphone version also shares the same play data and story setting of PSO2, but you can play the game independently from PC/Vita. The Smartphone version plans to release on both iOS and Android systems. This version allows for a single player experience, with the same weapons and enemies like in the PC/Vita version.
