Hi, Greenlaw
Currently we do not use any specific features of Kinect for Windows, so there is no much sense in replacing any of Kinect for XBOX for using with our software.
ASUS Xtion Live may be more convenient to use than Kinect by the following reasons:
- It is more compact
- It does not require external power source
- Mutual infrared interference is noticeably lower with Xtions
As for PS Move vs Wii Motion Plus, our thoughts are that PS Move is more advanced device, so we consider it as a primary motion sensor model in our development. Support for Wii Motion Plus is some sort of "backup" for those users who already got this device. Though we'll try to maintain this support at the best level we can.
