**Disclaimer** Now, I don't personally own a Zebralight, nor do I know any one who does. Neither have I read all of the posts on this thread. What is posted from here on in seems logical (at least to me).
Now, I am not exactly sure whether or not the new lights discussed here will still be 90* type lights, or more like a regular flashlight. However, it seems logical to me that the only way to keep a 90* format light with a reflector contained within roughly the same dimensions as the original light are to make it slightly longer, and, instead of mounting the LED next to the driver, with a heat sink, to mount the LED/reflector assembly on a smaller heat sink (which only gaps the span between the LED's base, and the internal arc of the body), on top of the driver assembly. This way you maintain the sleek appearance of the light, as well as near original dimensions for diameter, and length.
If the actual design of the unit is discussed anywhere in this thread, then disregard my thoughts (unless you work for Zebralight, in which case I'll let you use the aforementioned design for extremely cheap.
)
