It doesn't matter.. IMO.
They get lighter each year which is all that matters. It may be a liability thing as well. Maybe the guy who sued subway for getting 11" foot-longs is a boarder? Can't be to careful these days
To many products to bother really, Bikes can be significantly heavier than other brands and affect the rider more than a snowboard. I'd say the Never Summer boards are some of the heavier boards I've owned, but I still like them.
... Excluding the antiques I used to ride, haha.
