Here's the official scoop from Mazda North America...I actually spoke with a person who cared enough to inquire with the correct department to find out the total/colors produced:
1500 total including Canada
1180 blue
320 yellow
Mine is #1469, yellow
Hope this clears up the confusion!
Also, if interested...production begins on the RX-8 in late 2002, as a 2003 model.
