With regards to the orange and black colors, I have to agree that there are some out there like myself that would prefer a black color option - at least the rims and brain.
In the USA, orange and black colors are usually associated with either the Halloween holiday or highway construction zones. Take a look at the pictures of the kit, then close your eyes and try to imagine a gloss black finish on the rims, brain and possibly even stands and hardware. It would have a stealth look with a very sleek luxury to it, like a black stretch limousine.
This may be a cultural thing and don't get me wrong, I would still want one with the current color scheme. However, if they ever become available in a black color in the future, then my orange and black one would end up on ebay. Time wake up and go back to work!
