yeah tried at PSX in 2014 and at CES this year. its ok if you haven't used an oculus/vive at all, but once you have the Morpheus is kind of a joke. Visual display isn't anywhere near as good, the headset doesn't feel as comfy, there is no IPD to adjust for your head/eyes, and the move controllers feel pretty retarded like using the wii. The visuals don't come even close, while you don't really notice pixels per say the hud doesn't feel nearly as immersive, you always just feel like you are watching a screen.
i'm still gonna buy one since i assume there will be some PS4 exclusives that will be fun to try, but not in any rush - probably black friday sale. Also there will be no VR porn since all content will have to go through the PSN store.
