The only interesting and potentially badarse light, so far, is Streamlight's new HL4, dual fuel (4-cr123's or 2 18650's), optic and 2200 lumen output. SL is also coming out with their own 18650's (probably Samsung cells that they also use in the Strion cell) and a simple charger.
May have to keep an eye one the streamlight. Wonder which C4 LED they will use to get 2200 lumens? In all seriousness do you think we may see an mt-g2 or xhp50 offering from Streamlight?
