Count me in, Pal. I'd also like to see the same principle applied to flashlight bulbs, unless it can be demonstrated that they are clearly superior (such as the move to longer-lasting L.E.D.s).

I have a Surefire with a bulb life measured in hours - and not many of them at that. The lithium battery has a great shelf life, but doesn't last long in action.

I suspect the constant introduction of new batteries has more to do with m-o-n-e-y than with improved performance.
