I wasn't actually asking threadstarter to wait but more to tell CrashKing that all is not lost for having bought the Gladius among the Cree craze. It is a very good light in itself, and if there's a new Luxeon, it will be even better.
Don't wait forever but don't just on the absolute latest either; you will be out money and technology. Usually the 2nd revision comes out soon after; better and for around the same price. Or a competitor responds.
For example, let's say Fenix throws out the L1D-CE first at $55 (pure example as I dunno the price) and you grab it just cuz its a Cree light. In just a week or two, a competitor comes out with a 95% similar light for half the price. and maybe another month from now, the L1D-CE will be fitted with Q3 bins. I guess catching the right time is ideal, though that is easier said than done
