I think it's safe to say the Model X did not launch with Autopilot 2.0, much less Autopilot 1.1. No matter how you slice or dice it, there are no announced or observed enhancements to Autopilot hardware at the launch event. The press release from last night lists the exact same hardware as the original Autopilot. Furthermore, Tesla has made it clear the X and S will have feature parity on Autopilot. So, when a hardware upgrade comes, both models will start coming off the line with it.
On another thread, someone stated Autopilot was disabled on Elon's car despite having 7.0 software. Because of this, I do not believe it has been activated yet and they didn't want his car to be showing beta software. I believe it will be "turned on" in about a month at the same time for both the S and the X. (Of course, it's highly likely the first 4 Founders would be invited into the beta program.)
Again, the Model S 7.0 Release Notes specify "Blind Spot Prevention" has been upgraded to "Side Collision Avoidance." Yesterday was Tesla's first official announcement of the feature, but it was previously leaked as a feature for the Model S with Autopilot 1.0 hardware. I don't see any reason why "Side Collision Avoidance" on the S and X would be called the same exact thing and function differently.
I have never doubted incremental upgrades. However, I always highly doubted that the hardware would splinter before 1.0 was fully utilized. At this point, we should turn the speculation to when we'll see Autopilot 2.0 on both the S and X. Eventually we will see new Autopilot hardware, but it wasn't with the X launch. My prediction is that we'll see major Autopilot upgrades as their own announcements, independent of car model.
