I've been conversing with Gene regarding the choices for LEO's from the Malkoff range, they way I see it there are 3 B's for LEO's, Belt Light, Back-up Light and Bag Light.
IMHO the belt light is well covered by the M91T MD3 for reasons that I've expanded on in other threads, the E2T MDC 2 x CR123 (16650 body) would make an ideal back-Up light.
When it comes to the bag light, a light that sits in the officers kit bag in the cruiser and only comes out for extensive searches or prolonged uses, I mentioned that it would be useful to be able to run 2 x 26650 batteries, for instance the Hound Dog would be able to run 1000 lumens for three hours, which would be a huge step up from 18650's.
Any how, Gene mentioned that 1 x 26650 and 2 x 26650 bodies are in the works and should be available in the first half of 2017, he didn't say which heads they will be compatible with, but if he's investing in machining for the new Hound Dog Super it would make sense for the new bodies to be compatible with that, if the Hound Dog Super is compatible with the MD2/3/4 bodies then maybe the older versions of the Hound Dog and Wild Cat will also be able to benefit from the extended run times that the new 26650 bodies will provide.
