Wade, its a pro and con thing, i feel for the dealers who have to deal with ever changing models. Who wants to buy a cree p4 when you can guy a Q5 ? And the people who love flashlights like myself, would upgrade at least bi-update. I decided not to get a rebel, because i had a feeling they would make a Q5, even though they told me they would not make a Q5. If i had bought a rebel based on the communication from fenix that they told me they would NOT be making a cree Q5 light, i would be so annoyed you would not be able to restrain me.. I dont have money to throw around buying every flavor of light in the same model... If the body was different or something, smaller, larger or something i may buy every one in time. but to release 3 versions of a light that look and feel the same, but they only change the led, thats crazy. I think they should at the very least release cheaper flashlight heads, so you dont have to buy a whole new light if you dont want to.
