I'm still using BH 2.1.6 and it will do me for a while until maybe a Duo3 comes out and if that ever happens then I will update the duo2's 2.1.6 to maybe a newer blackhole image. I've had a look and play with a Solo 4K box but I will wait a little longer to see if Vu products ever brings out a box to replace the duo2 with 4K capability on board. I was only after the 2.1.6 thread just in case members have added post in the last 6 months or so.
What do you think guys will Vu ever bring out a replacement for the Duo2?
