Yeah.
Only new lights I can see are the P1RZ-IB-DF and P1RZ-B-DFT (combat grip P1r peacekeeper with intellibeam and 1500 lumens)
Even then they are not in stock.
It basically starts on High (550 Lumens) on the first press of the tailcap. Press until it clicks for constant ON.
Press the button the 2nd time within about 2 seconds from the first press and it will switch to Low output (25 Lumens).
The switching method is also similar to the G2X Pro and 6PX...
Got the answers on their facebook page on March 9.

Two people asked about UI and release date. In short, the answer is mid-April and the UI is High-Low similar to the Defender series.
Surefire did post this on their facebook page on the 2nd of March:
"It's coming! If you haven't heard the Turbo series release date is coming up! https://www.surefire.com/collections/turbo/"
I think the tailcap is a clicky. If you look closely at the pics, the tailcap is screwed all the way down without room for tightening. The EDCL1-T/EDCL2-T however in comparison has ample space to twist/tighten. Unless of course they have a new version of the gas pedal switch.
