Implementing Dark AI into X9 is pretty much already decided, if you look at the most recent update. It contains scripts to specifically act as place-holders until DAI is implemented into the engine, so I guess it's pretty much a final decision.
As for ragdolls, I recall Lee saying that as soon as X10 is out and going, they were going to port that over to X9 as well. Cross your fingers, folks!
Isn't it a pity, now isn't it a shame?
