I already tried to pre-order, can't yet :p
The price is to be expected. At launch PSVR with camera and 2 move controllers was similar. $400 for the headset, $50 for the camera, $100 for a pair of moves. So $550 is pretty much the same price as the complete PSVR set was at launch.
No point waiting for a better line up, I'll get it now before the price goes up lol. The games will come, plus the launch line-up already looks like a lot of fun.
