Well I don't believe that he is the only one that has been quite in this matter.  It seems that the ppl in this post that have stated they have a working or psudo-working k16 (at least able to run on all 16 chips) have kind of fallen off the map as well.
Steamboat's group buy/assembly have been trying to contact them in order to resolve thier issues with only being able to hash across 8 of the 16 chips.

I am sure they are all hard at work trying to sort out the issues, its hard to troubleshoot and keep up with all the posts at the same time.  Everyone is just rather impatient because of investments that we have made/going to make.  This is pretty bleeding edge development, things take time and road blocks through everything out of wack.  IMO its better to be focused on the troubles at hand then doing PR work.
