If you're waiting for Calmini to come out with an SAS kit for the 2nd gen you're probably (let me emphasize the probably here) never ever going to see one...from Calmini or others.
The reason I say this, is because I was present for quite a bit of the fabricating of Ponyboy's SAS by the guys @ All Phase.
Not only was it expensive, there was a lot of monkeying around that had to be done to swap from rack and pinion steering to a traditional drag link/centerlink setup.
But, having said that, if enough people push the manufacturers they might just suprise us.
