I see that a new lumin u2 ( not the mini) has been released. Not much blurb on it at the moment though. The power supply is inbuilt now and seems to come with a fiber optic input like the P1.
6 moons was err slightly wrong . The U2 is not a replacement for the U1 per se. The U1X is still their flagship. There is a replacement of the U1X on the horizon, which should be their new flagship transport. The next gen X1 will be built with that upcoming digital streaming section.
I have reliable user auditions from Hong Kong which claim that the U1X still betters the U2 by some margin. So the U1X replacement should be better, but will be way more expensive than the current pricing.
