Looks like the 2.0 is on available on Amazon now:

I have the earlier version on a Surefire G2X Tactical (a pretty good buy for an all purpose hand held at its going price, BTW, if you are okay running CR123s). I don't use the Thyrm switch in the intended weapon light grip, but it draws from the pocket into a hammer fist/neck index nicely. The new model seems like it has some good improvements. I may give it a shot.
