The new WRX came out in Japan/UK/Australia last month - last time I looked at the calendar, this was the year 2000.
You are mixing the concept of the "Model Year" - a strange concept used by American car manfacturers and importers to promise much, but deliver little - with actual calendar year. I prefer talking about actual year because it removes ambiguity. The WRX is coming out in America in Spring of 2001 (March? April?) as, confusingly, a 2002 car (I just don't see how that makes any sense).
