Earlier in the year SureFire placed the new L5 on indefinite hold.
SureFire have since released their new L1, new E1L, new E2L, new 6PL, new G2L and new Titan. And those are just the high-profile flashlights... Most noteworthy for WeaponLight has been the release of the new X300.
Perhaps SureFire prioritised the releases and in due course will look again at the new L5.
It seems to me that high output bezels for the likes of the M2/C2/L5 (6P) body, and looking further into the mists - for the M3 body are strong contenders for update...
