In water buoyancy is more important to me than out of water weight. I know of several manufacturers that don't want those specs published...
LMI's ROC controller is really two parts, remote control of the camera, and a strobe guide number controller built into the grips. Having used this housing for the past 18 months, I agree with Joe's comments.
If I were a housing builder, I wouldn't bother incoporating remote camera control, as it is a bit of reinventing the wheel. Ergonomically placed mechanical controls are more intuitive to use, in my opinion, and Subal, Seacam, and Nexus have proven that they can be placed at the photographers fingertips.
ROC strobe control is another story entirely. Ikelite has a very similar system on their new canon systems, allowing manual strobe control from the housing back. ROC builds good exposure habits, making the photographer more likely to adjust strobe output than aperture. It is very convenient.
Light & Motion intended to build for the d70 camera, but it was incompatible with their ROC Camera Control (meaning they would have had to use mechanical controls for shutter speed and aperture). My guess is they canned the project because the housing would have been much later to market than their competition.
If the d100's replacement offers the same remote control layout as the d100, and fits in the same casting, it is a very safe bet that light & motion will house it.
