When the dropper post is extended, the saddle sits level. When slammed, the nose of the saddle would automatically be angled upwards slightly. A level saddle is ideal for climbing, but most downhillers (and dirt jumpers) prefer to angle their seats slightly. This helps improve control and makes it easier to hang off the back and control the bike with the thighs.
How far out is the new tech? We can only speculate, but we do find it interesting that the new Specialized Enduro ships with a 34.9 seat tube. Specialized does not offer a 34.9 dropper, so the existing bikes ship with a shimmed post.
