Well, I don't mean to get all Jacob ants-in-pants-y about Mazda3s, but historically, they've been great sellers, the 6s, not as much, although they've steadily been getting better. And they adjust their manufacturing numbers to try to match anticipated sales, so they may have just not anticipated how much better the 6 was going to sell this year vs. the 3.
And thanks for your impressions, I didn't realize the WRX had gotten that much bigger, it (as the Impreza) used to be significantly smaller. Sounds like you got exactly what you were after.
