It's not the end yet, but it will get dated... look at it this way... There are still hundreds of thousands of socket 478 systems out there right now... they are not going away any time soon... they will still support them until the bitter money making end... So S939 will still be around... and oh by the way, it's not that old so IMO it's the most reliable and solid system out there right now even with the new cores coming out... they are still so new that no ones really making anything for it... yea there are a few boards, and what not, but NOTHING compared to the S939 systems. So give it a few years and then you might see the S939's going the way of the Dodo...
