It might be smarter for them to make a "Pro Team" line, as a step above the Factory Team line, and only do them in small batches, annually; i.e. 2008 Pro Team LE RC8, with big bores, capture plates, aluminum upper, a tank that works, and maybe a couple other small things (optional 17T included?). That way, they're not diggin themselves an overstock hole, but at the same time, they are catering to the racers... and who knows, maybe a few high-paid bashers would want one as well.
From a company standpoint, releasing a "Worlds" edition would probably garnish a bunch of boo-hoos from the crowd that knows the RC8 didn't podium at the worlds. Concurrently, those who watched will know how strong they really were, and maybe want to shell a little extra coin for the popular upgrades. Most companies don't have the overhead, especially nowadays, to produce elite level kits en masse.
AE could sell out of 100 RC8 "Pro Team" yadda yaddas in a heartbeat. 500? Probably not.
