i'd rather see custom straps than a whole new themed goggle.
it could work like burton classifys there apparel, in a specific color set. like white would have a bunch of limited straps, black would have some, etc. for all the different colors, and they would all match depending on the color scheme of your frame.
good idea though. i'd take a white strap with black ns logo on it. like a big one where the O is.
