As Monkeyboy stated, SF's release dates have been inaccurate time after time. I still consider it good news that they gave you a month and date rather than a season.
I think the concept is neat and the size will be great, but once again, it's hard for me to become too excited until the price is released. With up to 5000 lumen capability, I have a feeling that it's going to be much higher than the anticipated figure of $1500, in which case the Polarion X1 is still fantastically attractive in the "high-end" range of HID.
