I don't want to take us too far off topic, but does lighter plastic neccessarily mean lower quality? I mean the processes and blends have come a long way, it is possible that the plastic they are using could be stronger or just as strong even if there is less of it.
On topic... I'd love to see a revival of this theme! I'm with Ras that new colors would be nice so that you can tell the difference between new and old easily, as long as the new colors are realistic and not PINK or something.
New parts would be great, too!
