Don't know whether some of you are aware of it or not but still felt like sharing with you guys, the existing Playstation Move controller will work with Playstation 4 (PS4).
The confirmation of this came from Shuhei Yoshida, President of Worldwide Studios, Sony Computer Entertainment on Twitter. Shuhei Yoshida also confirmed that DualShock 3 controller will not compatible with PS4. So guys if you have any PS Move controller don't trade them just yet.
@Bowldylocks DS3 no, Move yes
