It does not change the fact that a 2016 release for Zen means them releasing them for any market Zen might be launching in. Bulldozer shipped in August 2011 to supercomputer customers like ORNL.
The problem with enthusiasts is that they instantly saw 2016 as the release date for Zen and instantly thought it was the AM4 release. You only have to blame yourself for made up hype that it would be launching now for enthusiasts.
Yes the problem with enthusiasts is that we like to see what AMD themselves post and take it that when they show slides saying desktops Zen CPU's for 2016, we assume they actually mean desktop CPU's for 2016.
