well, apparently Snady Bridge will be out in a matter of months, so id say Bulldozer would be out soon afterwards...
the main thing that worries me is what will the prices be?
According to some sources AMD has delayed Bulldozer until Q4 2011. It was slated for Q2 2011 but the 32nm fabrication process GloFlo is working on is having a few problems they need to sort out. Most likley its a problem with yields since I think AMD is still using SOI and adding HK/MG too it in 32nm.
Who knows until AMD says something concrete.
